01About

Engineered
by curiosity.

I build things that work — fast, secure, and at scale.

As a Mechanical Engineering student at NIT Delhi who codes full-stack, I bring an engineering mindset to software. I'm obsessed with system design, backend architecture, and building products real people use — across web, mobile, and offline desktop.

My toolkit spans the entire MERN stack plus React Native for mobile and Electron for offline desktop apps, with a strong grip on security (JWT, RBAC, cryptographic licensing), queue-driven workflows (BullMQ + Redis), real-time systems (Socket.io), and AI-powered features using RAG architectures with Pinecone, HuggingFace Embeddings, and Groq LLM. I actively practice DSA in C++ to keep problem-solving sharp.
