## Projects

### Gym CRM

**Type:** Desktop / Full-stack
**Date:** 2026-07-16
**GitHub:** https://github.com/PRATHAM1ST/gym-crm-electron

#### Description

A polished, local-first gym management desktop application built with Electron, Vue 3, and TypeScript, targeting daily front-desk use at The Big Biceps Gym. The Electron main process hosts an in-process Aedes MQTT broker and a better-sqlite3 database accessed via Knex, exposing all data operations to the renderer over typed IPC channels — no separate server process is required. The renderer (Vite + Vue 3 + Tailwind CSS + Shadcn/reka-ui) covers member and employee management, QR-code check-in/check-out, attendance history, finance with ApexCharts income/expense breakdowns, WhatsApp message templating, and GST-aware receipt and pay-slip generation via jsPDF. A companion Next.js admin dashboard (server/) manages API keys and licensing for deployed instances, backed by Redis. An ESP32-S Arduino sketch (`hardware/QR_Scanner_Optimized/`) provides a physical QR scanner: it runs FreeRTOS dual-core tasks — camera capture on Core 0 and quirc QR decoding on Core 1 — and publishes decoded QR results to the Electron hub over MQTT via WebSocket, enabling hands-free member check-in without a USB barcode scanner.

**Tech Used:** Electron, Vue.js, typescript, Vite, Tailwind CSS, shadcn, better-sqlite3, Knex, MQTT, Aedes, ESP32, Arduino, ApexCharts, Next.js, zod

#### Difficulties Faced

Packaging an Electron app with native Node modules (better-sqlite3) using electron-forge + Vite required a custom `ignore` function in the forge config to include `node_modules` in the ASAR bundle while keeping `*.node` binaries unpacked, since the Vite plugin's default packaging omits runtime dependencies. On the hardware side, the ESP32 QR scanner had a series of concurrency bugs: WebSocket send/receive was called from multiple FreeRTOS tasks simultaneously (unsafe), non-atomic counter increments across cores produced corrupted stats, and a null-deref in the quirc decode loop could crash the device — all fixed by funnelling WebSocket ownership to a single IoT task and adding atomic operations and null guards.

#### Things Learned

Building a full hardware-to-desktop IoT pipeline in a single repo clarified how to bridge the physical and software layers cleanly: the ESP32 owns the camera and decode, publishes a single QR string over MQTT, and the Electron main process owns all business logic — keeping each layer's responsibility clear and the protocol minimal.

### RG Games

**Type:** Full-stack
**Date:** 2026-07-15
**Live:** https://rg-games.vercel.app

#### Description

A gaming-events booking platform where users browse events, reserve spots, and pay via Razorpay or Cashfree — the checkout route selects the active payment provider at runtime and handles free (₹0) events by confirming directly without creating a payment order. Admins manage events, upload poster images to Supabase Storage, track bookings, manage player records, schedule sessions, and record match results including leaderboard data. Built on Next.js 16 App Router with Drizzle ORM over a Supabase Postgres database.

**Tech Used:** Next.js, typescript, Drizzle ORM, postgresql, Supabase, Tailwind CSS, shadcn, Razorpay, framer motion

#### Difficulties Faced

Integrating two payment providers (Razorpay and Cashfree) through a single abstracted `getPaymentProvider()` interface required careful handling of webhook verification, order-ID namespacing (`rg-<bookingId>`), and the edge case where Cashfree rejects sub-₹1 orders — free events had to bypass payment-order creation entirely and be confirmed server-side directly from the DB price field, never trusting client input.

#### Things Learned

Modelling dual payment providers behind a shared interface keeps the checkout route clean and swappable, but each provider's webhook signature verification is distinct enough that it must stay in its own handler. Separating the Supabase service-role key (server-only storage uploads) from the anon/publishable key (database client) is critical to avoid accidentally exposing elevated credentials.

### DeBruycker Charolais

**Type:** Mobile / Full-stack
**Date:** 2026-07-11

#### Description

A companion product for the DeBruycker Charolais annual bull auction, consisting of a cross-platform iOS and Android app and its dedicated backend service. The mobile app — built with .NET MAUI 10 and the MVVM pattern via CommunityToolkit.Mvvm — lets auction participants browse the full bull catalogue, filter lots by pedigree metrics (ABW, AWW, ADG), watch herd-sire videos, save favourites, and track upcoming sales with a countdown banner. It is offline-first: data is fetched from a Railway-hosted middleware and cached into an on-device SQLite database so the catalogue remains accessible without a connection. The backend (Middleware) is a Bun + TypeScript service that receives full auction payloads via a webhook from Superior Livestock, transforms them into the app's exact PascalCase contract, stores them in a server-side SQLite database (using `bun:sqlite`), and serves them to the app via a versioned REST API with incremental sync and API-key auth.

**Tech Used:** .NET MAUI, C#, CommunityToolkit.Mvvm, SQLite, Bun, typescript, Railway

#### Difficulties Faced

Coordinating compile-time backend URL switching across three environments (local, staging, production) in a .NET MAUI project — where Debug packaging semantics differ from Release — required decoupling environment selection from build configuration using MSBuild properties rather than a third `-c Staging` configuration, which would produce a standalone APK that crashed on launch. The middleware's delete-and-reinsert sync strategy had to be made safe to run at boot on staging (seeding from live production data) while guaranteeing it could never run on production, enforced by a guard that fails closed unless `SEED_ON_BOOT=1` and the environment is not production.

#### Things Learned

Building an offline-first mobile app that preserves client-side state (favourites) across server-driven data refreshes requires keeping that state in a separate column that the sync logic deliberately re-applies rather than overwrites. Working across a monorepo where the mobile app and backend share a data contract taught the value of having the server's field-mapping table and the app's `BullModel.cs` as the single source of truth for the API shape.

### Taekwondo Academy Platform

**Type:** Full-stack
**Date:** 2026-06-12
**GitHub:** https://github.com/PRATHAM1ST/taekwondo-webapp

#### Description

A complete academy management platform built with Next.js 16 and Prisma on CockroachDB, serving two distinct portals — a student-facing view for attendance history and profile, and an admin portal for student management, payment tracking, attendance marking, CMS page editing, and inquiry handling. Payments track due dates, PENDING/PAID/OVERDUE status, and grace cycles; a cron-triggered API route (secured with a bearer secret) queries upcoming and overdue payments, then fires email reminders via Resend and generates WhatsApp `wa.me` deep links with pre-filled messages using libphonenumber-js for E.164 normalization. Role-based access is enforced through NextAuth v5 with bcrypt-hashed passwords and brute-force lockout.

**Tech Used:** Next.js, React.js, typescript, Tailwind CSS, shadcn, prisma, postgresql, NextAuth, zod, framer motion, Resend

#### Difficulties Faced

Designing a payment-reminder system that is both idempotent and multi-channel required pairing each alert type (PAYMENT_DUE, PAYMENT_OVERDUE, COURSE_ENDING) with a deduplication check in the database before creating an `AdminAlert`, so repeated cron invocations on the same day do not generate duplicate notifications. On top of that, WhatsApp reminders needed phone numbers normalized to E.164 format (defaulting to the India locale) before building `wa.me` links, adding a validation step that silently drops malformed numbers rather than generating broken links.

#### Things Learned

Storing alert records in the database as the deduplication key — rather than relying on cron timing precision — is the robust approach: it survives retries, manual re-runs, and schedule drift without any additional state management.

### CQRC — AI Support Chatbot

**Type:** AI
**Date:** 2026-06-01
**Live:** https://cqrc.vercel.app

#### Description

A RAG-powered support chatbot with an admin dashboard where operators upload PDF, DOCX, and XLSX knowledge sources or define custom Q&A pairs. At query time the app runs BM25 retrieval over chunked document text stored in Upstash Redis, combines the top-k chunks with matched Q&A pairs into a grounded context prompt, and streams the answer back — refusing to speculate outside the uploaded knowledge base. Conversation history is persisted per session so follow-up questions stay coherent.

**Tech Used:** Next.js, typescript, Upstash, Tailwind CSS, shadcn, Prompt Engineering, AI Agents

#### Difficulties Faced

Without an embedding model, relevance scoring had to be done with a hand-rolled BM25 implementation over tokenized text stored as JSON blobs in Redis lists — this required computing IDF per query term across all chunks on every request, which works for small-to-medium corpora but means the Redis pipeline fetches every chunk eagerly. Handling three distinct file formats (PDF via pdf2json, DOCX via mammoth, XLSX via xlsx) each with their own parsing quirks and chunking strategies added significant branching in the file-processor layer.

#### Things Learned

BM25 over Upstash Redis is a practical zero-cost alternative to vector search for domain-specific corpora where the vocabulary is controlled; the trade-off is that synonyms and paraphrases are invisible to the scorer. Weighting Q&A question-token matches higher than answer-token matches noticeably improves precision for FAQ-style queries.

### ProofMarket

**Type:** Web3
**Date:** 2026-03-17

#### Description

A creator-backed Web3 protocol built with Solidity, Hardhat 3, and OpenZeppelin, deployed to Ethereum Sepolia. Creators register projects and receive PMT (a capped ERC20 with votes and permit) from supporters; each supporter receives an ERC721 badge NFT with ERC2981 royalties. The protocol includes a PMT-only NFT marketplace with royalty-aware purchases and treasury fee routing, a time-based PMT staking contract, and a full OpenZeppelin Governor + TimelockController governance system. A TypeScript event indexer materializes on-chain state to a local JSON file for the frontend, and the Next.js dApp uses a single `useProofMarket` hook that connects to all six contracts via viem public + wallet clients.

**Tech Used:** Solidity, Hardhat, Viem, Next.js, React.js, typescript, Tailwind CSS, OpenZeppelin

#### Difficulties Faced

Coordinating deployment order and cross-contract role grants across eight interdependent contracts (Treasury needs to know the Marketplace address, Governance needs the Timelock, Staking needs the token minter role, etc.) without a proxy pattern meant the Hardhat Ignition module had to express the full dependency graph explicitly, and any circular reference would deadlock the deployment. Additionally, the governance contract had to use the production Hardhat build profile because the bytecode size of the optimizer-disabled Governor exceeded the EVM contract size limit.

#### Things Learned

Hardhat Ignition's declarative dependency graph forces you to think through the full cross-contract permission surface before deployment, which surfaces role-grant bugs at module-definition time rather than at runtime on a live network.

### IdLocker

**Type:** Mobile
**Date:** 2026-01-09

#### Description

A fully offline React Native vault app for storing bank account details, credit/debit cards (last 4 digits only — no CVV), government IDs (Aadhaar, PAN, Passport, Driving License), login credentials, and secure notes. All data is encrypted at rest using `expo-secure-store` (iOS Keychain / Android Keystore) with a 2 KB chunking strategy for large vaults. The app enforces biometric authentication (Face ID / Touch ID / Fingerprint) with device PIN fallback, auto-locks on background, and prevents screen capture on all sensitive screens — no network calls, no analytics, no cloud sync.

**Tech Used:** React Native, Expo, typescript

#### Difficulties Faced

expo-secure-store has a per-key size limit of 2 KB, so storing a user's entire vault as a single blob requires a chunking layer that splits the serialized JSON across multiple keyed entries and reassembles them on read — getting chunk boundaries, ordering, and partial-write failures right without data corruption is the core storage challenge. Screen capture prevention (`expo-screen-capture` / Android `FLAG_SECURE`) is not enforced uniformly across all Android ROM variants, requiring explicit documentation of the known ceiling.

#### Things Learned

Device-local security is only as strong as the device lock itself — the app's threat model had to document exactly what it does and does not protect against (ADB backups blocked via `allowBackup: false`, but a rooted device bypasses Keystore). Biometric changes (adding/removing fingerprints) can silently invalidate Keychain/Keystore entries, so the onboarding flow needs to warn users before they enrol new biometrics.

### Fabric Inventory (GenUI)

**Type:** AI
**Date:** 2025-12-19
**GitHub:** https://github.com/PRATHAM1ST/fabric-inventory-genui

#### Description

A conversational fabric inventory management system where the UI itself is generated at runtime by Thesys C1 — instead of pre-built forms, the AI assistant responds to natural-language queries and streams back rendered UI components (tables, lists, summaries) via the `@crayonai/react-ui` C1Chat component. The system prompt instructs the model to confirm destructive actions and display structured inventory data in tables rather than prose.

**Tech Used:** Next.js, typescript, Tailwind CSS, AI SDK, Prompt Engineering

#### Difficulties Faced

Generative UI via Thesys C1 means the rendered interface is non-deterministic — the system prompt has to be precise enough to enforce consistent output formats (tables for inventory data, lists for instructions) without over-constraining the conversational flexibility. In-memory message storage means conversation state is lost on server restart, which is acceptable for a demo but would need a persistence layer for production.

#### Things Learned

Thesys C1's streaming generative-UI pattern (`@crayonai/stream`) decouples the AI response from the rendering layer so React components can appear progressively as the model outputs structured tokens — this is a fundamentally different mental model from traditional chat where you render the text and handle UI state separately.

### Only Gossips

**Type:** Full-stack
**Date:** 2024-05-15
**GitHub:** https://github.com/PRATHAM1ST/Gossip

#### Description

An anonymous gossip-sharing platform where users post text or image content without signing up. Posts support emoji reactions, view tracking, and sharing; readers can report violations. An admin panel moderates flagged content. Built on Next.js 13 with a PostgreSQL database via Prisma and image uploads through Cloudinary.

**Tech Used:** Next.js, typescript, Tailwind CSS, Radix UI, prisma, postgresql, Cloudinary, Material UI

#### Difficulties Faced

Tracking views and reactions anonymously without user accounts required a lightweight fingerprinting approach using IP address hashing (`request-ip` + `crypto-hash`) and UUID-based session identifiers, so the same visitor could not inflate counts while still keeping zero personal data on the server.

#### Things Learned

Designing a database schema (Prisma models for Post, View, PostReaction, ReactionsList) that enforces uniqueness constraints at the DB level was more reliable than trying to deduplicate in application code.

### Whisper Verse

**Type:** Full-stack
**Date:** 2024-05-07
**GitHub:** https://github.com/PRATHAM1ST/whisper-verse

#### Description

A story browsing and writing app built with Next.js 14 App Router. Readers browse stories by genre category (Love, Happy, Tragic, Horror) and individual story pages.

A single Node.js/Express backend built for the Techholding Hacknuthon 2023 that serves data over three protocols simultaneously: a REST API with full CRUD, a GraphQL endpoint backed by MongoDB, and XML↔JSON conversion middleware. Incoming XML bodies are parsed and cleaned before storage; stored records can be retrieved as XML via `GET /jsontoxml/:id`. Password hashing uses SHA-512 via `js-sha512` and all routes sit behind a shared auth router.

**Tech Used:** Node.js, Express.js, mongoDB, graphql, javascript

#### Difficulties Faced

The main challenge was handling XML bodies in the same Express app that also accepts JSON — `express-xml-bodyparser` parses XML into nested arrays of single-element objects, so a custom `cleanParsedData` function was required to recursively unwrap those arrays before the data could be stored or returned cleanly.

#### Things Learned

Building one server that speaks REST, GraphQL, and XML at the same time forces you to think carefully about middleware ordering and how body parsers interact; registering `xmlbodyparser()` after `express.json()` and routing each protocol to its own sub-router kept the concerns cleanly separated.

### WaterTank IoT Alert

**Type:** Embedded/IoT
**Date:** 2023-02-10
**Live:** https://watertank-server.vercel.app
**GitHub:** https://github.com/PRATHAM1ST/watertank-server

#### Description

An ESP32 mounted near a water tank reads a capacitive touch sensor and a voltage sensor every 500 ms; when both readings indicate a full tank for 5 consecutive iterations (a debounce guard), it fires an HTTP GET to an Express server hosted on Vercel, which then places a Twilio voice call, sends an SMS, or dispatches a nodemailer email warning the owner to turn off the motor. The three alert channels (call, SMS, mail) are independent REST endpoints so the `.ino` code can switch between them by changing one line.

**Tech Used:** ESP32, Arduino, Node.js, Express.js, Twilio, javascript

#### Difficulties Faced

Capacitive touch readings on the ESP32 return 0 when the sensor is submerged, which is also the value seen during noise spikes — a single-sample check caused false alerts. The fix was a confirmation counter requiring 5 consecutive positive readings before triggering, with the counter resetting to zero on any non-full reading.

#### Things Learned

Physical sensor signals are noisy and a bare threshold check is almost never enough; a small iteration-based debounce in the microcontroller firmware is simpler and more reliable than trying to filter on the server side.

### ESP32 Cloud Sensor Logger

**Type:** Embedded/IoT
**Date:** 2023-02-05
**GitHub:** https://github.com/PRATHAM1ST/esp32-arduino

#### Description

An ESP32 paired with an Adafruit MPU6050 accelerometer logs temperature, acceleration, and gyroscope readings to the cloud via a Blues Notecard module every 5 seconds. The Notecard handles connectivity and queues sensor payloads as JSON notes, removing the need for the firmware to manage network reconnection logic. The project is published on Hackster.io as a full tutorial at hackster.io/the-esp32-elite/mobile-cloud-storing-sensory-data-using-esp32-4a0023.

**Tech Used:** ESP32, Arduino, C#

#### Difficulties Faced

Coordinating two I2C devices (MPU6050) and UART (Notecard) on the same ESP32 required careful pin assignment and initialization order in `setup()`; the Notecard also needed its product UID configured before any note requests would be accepted.

#### Things Learned

The Blues Notecard abstracts away all cellular/Wi-Fi reconnection and queuing, which means firmware can stay focused on reading sensors and formatting JSON — offloading connectivity to dedicated hardware significantly reduces firmware complexity.

### Question Generation AI

**Type:** AI/ML
**Date:** 2023-02-01
**GitHub:** https://github.com/PRATHAM1ST/Question-Generation-AI

#### Description

A fine-tuned transformer pipeline that takes a passage of text and automatically generates question-answer pairs from it. The system uses T5 (via HuggingFace Transformers) in two stages: an answer-extraction model identifies candidate answer spans highlighted with `<hl>` tokens, then a question-generation model produces a question for each span using beam search (4 beams, max 32 tokens). Three pipeline modes are supported — standard QG, multitask QA+QG, and end-to-end QG — trained on the SQuAD multitask dataset with a custom `T2TDataCollator` and evaluated by decoding predictions to a text file for offline BLEU scoring.

**Tech Used:** python, HuggingFace, PyTorch

#### Difficulties Faced

Preparing inputs correctly for each pipeline mode was the central challenge: the highlight (`<hl>`) token had to be injected at the exact character offset of the answer span within its sentence, and the surrounding sentences had to be re-joined without corrupting whitespace, so a misaligned index would produce malformed prompts and garbled questions.

#### Things Learned

Seq2seq models are sensitive to prompt formatting — the difference between `generate question:` and `extract answers:` prefixes, plus the `</s>` suffix required by T5, significantly affects output quality, making prompt engineering as important as the model architecture choice.

### Sentiment AI

**Type:** AI
**Date:** 2023-01-29
**GitHub:** https://github.com/PRATHAM1ST/Sentiment-ai-frontend

#### Description

A topic-driven sentiment analytics dashboard where users search a keyword and see live sentiment data pulled from Twitter, Reddit, and meme feeds via a WebSocket stream. Charts built with ECharts and Visx display top emotions, trending reactions, and volume over time. News articles and meme images render alongside the analytics in a single view.

**Tech Used:** React.js, javascript, ECharts, Visx, WebSocket

#### Difficulties Faced

Rendering multiple real-time data sources (Twitter sentiment, Reddit threads, memes, news) from a WebSocket stream in a single coherent UI required careful state isolation per component so that a slow meme feed would not block chart updates.

#### Things Learned

Keeping each data-source component self-contained with its own loading state — rather than lifting all WebSocket data to a single parent — made the dashboard noticeably more responsive and easier to reason about.
