What I'm looking for

I'm looking for opportunities to build full-stack web products, contribute to real user-focused features, and grow through collaborative engineering work.

I've built full-stack platforms including a Duolingo-inspired Spanish learning product with courses, exercises, XP, streaks, skill progression, and leaderboards.

For Kumar Kosmetics, I created personalized product discovery based on skin type, concerns, and allergies, integrating Razorpay payments, wishlists, carts, order tracking, secure authentication, Redis caching, and optimized MongoDB queries.

I also built Skill Bridge, an AI-based career guidance platform that generates personalized learning roadmaps, course recommendations, and progress tracking using Gemini API and JWT authentication.

I'm pursuing a B.Tech in Computer Science and Engineering at Lovely Professional University, and I contribute to open source through meaningful UI and bug fixes, earning a Hacktoberfest 2025 Super Contributor Badge.
