I've built production-grade backend systems, full-stack apps with real-time features, and AI-powered SaaS products. Here are a few highlights.

Eatly — AI Menu Analyzer SaaS

A freemium SaaS product built around a real problem — you never really know what's in restaurant food. Scan any menu and Gemini Vision automatically extracts every dish, flags hidden ingredients, detects veg and non-veg items, and generates a health score with reasoning. Monetized with Stripe — free users get limited scans, Pro users unlock full dietary profile tracking across meals.

AI Food Delivery Platform

A full-stack food delivery web app with three separate user roles — Customer, Restaurant Owner, and Delivery Partner. Features real-time order tracking via Socket.IO and OTP-based delivery confirmation for security. What makes it stand out are three Gemini-powered features built into the core product: Semantic Search so customers find food naturally, a Hungry AI Chatbot for recommendations, and an Auto Menu Description Generator that helps restaurant owners write compelling listings instantly.
