Built the signup and account experience that 15,000+ international students use to get insured in the US. Owned it from the React/Next.js UI through TypeScript Node.js APIs, handling personal and policy data in a regulated domain. Also shipped internal tools and admin workflows the team uses daily, across PostgreSQL, FastAPI, GraphQL and Redis, deployed with Docker on AWS.

Built RAG-powered semantic search across member profiles and work for an invite-only professional network, covering the retrieval layer through the search UI. Cut load times by roughly 80% by overhauling the application's infrastructure, authentication, and rendering pipeline.

Built Muze CMO from scratch, a full-stack AI marketing platform that reads live Meta and Google Ads campaign and competitor data, predicts whether a creative will perform before spend, and generates the next ad. Designed the data and API layer on Supabase/PostgreSQL with Redis for real-time retrieval and caching, plus a RAG layer grounded in campaign, competitor, and brand data. Cut API latency by 40%, drove a 25% increase in user engagement, and overhauled CI/CD and Docker deploys on AWS (EC2, CloudFront, S3), taking deploys from days to hours.

Built InfiniteUGC end to end, an AI video pipeline that turns scripts into TikTok-native ads for 50+ brands across 32+ languages. Wrote the job orchestration and AWS render pipeline behind the long-running compute. Shipped Craft Trading, a React Native (Expo) paper-trading app for the Indian stock market, live on the App Store, with real-time price sync over Redis pub/sub and WebSockets.
