What I'm looking for

I'm looking to build impactful full-stack products, developer tools, AI applications, DevOps systems, or Web3 solutions where I can work on real technical challenges and grow through hands-on engineering.

I've built CodeSage, an AI repository assistant that indexes GitHub repositories using tree-sitter, Voyage embeddings, Pinecone, and retrieval-augmented chat. I improved retrieval accuracy from 66.7% to 100% across a 33-question evaluation suite.

I engineered a nine-tool agent loop for repository mapping, code search, and GitHub issue and pull-request access, with human confirmation for write actions. I also added PostgreSQL state persistence, Langfuse tracing, Redis embedding caching, GitHub webhook-driven reindexing, and BullMQ background workers.

I've also delivered real-time and privacy-focused full-stack products, including a collaborative whiteboard supporting 12 simultaneous users and a Chrome extension that summarizes reading and video activity with on-device WebLLM inference.

I build with Next.js, React, Node.js, Express, TypeScript, PostgreSQL, MongoDB, Redis, cloud tooling, and Web3 technologies. I'm currently pursuing a Bachelor of Technology at IIT Roorkee.
