About

I'm a full-stack developer who builds complete, AI-integrated products — not just prototypes. From a real-time social platform with LLM-powered features to a RAG-based document Q&A system, I've shipped end-to-end applications covering backend architecture, secure auth, real-time data, and cloud deployment. I combine that hands-on build experience with strong DSA fundamentals (200+ problems solved) and a track record of mentoring other developers as a Microsoft Student Ambassador
