AI agent that recovers failed payments, with a policy engine standing between every decision and real money. Built a custom agent loop that diagnoses each failure, then routes its recommendation through 4 fixed guardrail rules before acting on Razorpay. Across 200 failed orders it matched rule-based baselines 73.3% of the time, while payment-history analysis prevented duplicate charges on 34 cases.

Anonymous chat platform enabling secrets and mood-driven interactions. Leveraged Socket.io for real-time 1:1 and group chat, with Supabase powering the Confession Board. Engineered a fluid UI with Zustand and Motion, improving engagement time by 40%. Built as a full-stack Turborepo monorepo and deployed via Vercel and Render.

AI-driven design feedback platform with coordinate-anchored, role-based collaboration. Built a feedback pipeline using Google Gemini and the Vercel AI SDK with Zod-validated output. Engineered an Express/MongoDB backend in a Turborepo monorepo with role-based filtering for 4 roles, threaded comments, and JSON export; decoupled upload and analysis to cut AI costs.

Interactive polling platform with real-time updates and analytics. Built for live votes and reactions delivered instantly via Socket.io. Integrated Clerk authentication with lightweight APIs for secure user actions, and defined modular MongoDB models across all 6 REST endpoints.

Capstone project — a timetable generator with constraint-based scheduling. Generates conflict-free timetables using a Python OR-Tools CP-SAT optimization engine, with Redis worker queues and Express APIs for parallel schedule generation. Integrated Gemini AI for constraint parsing and conflict explanation; deployed via AWS and Vercel.
