React FastAPI PostgreSQL SQLAlchemy Async Clerk Gemini API

• Full-stack resume platform: React live-preview editor synced to a FastAPI backend, with a server-side Jinja2 + WeasyPrint pipeline producing pixel-identical, ATS-compliant PDF exports.
• Data layer built around PostgreSQL JSONB columns to persist semi-structured resume sections without rigid relational schemas.
• Ownership-aware authorization pairing Clerk RS256 JWT verification with request-scoped async DB sessions, closing an IDOR-style data-leak class common in simpler builders.

🔗 Live Demo

React Native Expo Zustand WebView KaTeX

• Cross-platform (iOS/Android) Expo app for GATE CS / competitive exam prep with a state-aware AI assistant that reads live app state via a global Zustand store.
• Rich notes module supporting markdown/KaTeX rendering inside a WebView editor, with import support from ChatGPT, Gemini, and Notion exports.
• Full productivity toolkit: syllabus parser, quiz engine with re-attempt tracking, epoch-based session timer, and reminders, all state-synced across the app.

Electron JavaScript SQLite Chart.js

• Production Electron billing app in active daily use at a real salon, optimized for sub-2-minute billing with phone-based customer autofill.
• Revenue analytics dashboard (daily/weekly/monthly, UPI vs. Cash, staff leaderboards) using Chart.js, plus WhatsApp bill-sharing and CSV export.
• Full UI redesign to a themeable dark-gold interface driven by CSS custom properties, preserving backward compatibility with the existing renderer bridge.

React Flask PaddleOCR MongoDB GPT-4o-mini

• B.Tech final-year project, awarded EX (highest distinction).
• Tuned a custom PaddleOCR pipeline for Indian packaging (grayscale, adaptive thresholding, box merging), reaching 85–95% OCR accuracy.
• JWT auth, bcrypt hashing, and MongoDB Atlas storage behind a Flask API, with GPT-4o-mini driving per-ingredient health analysis against user profiles.
