What I'm looking for

I'm looking to build practical backend, cloud, distributed, and agentic AI systems where I can deepen my engineering skills and contribute to real-world products.

I've built agentic AI applications with LangGraph and LangChain, including tool calling, memory management, RAG, MCP integration, and LangSmith observability.

I developed a full-stack e-commerce platform using Node.js, MongoDB, Prisma, and cloud deployment services, implementing authentication, product management, order processing, and database optimization. I also built a scalable real-time chat application with WebSocket-based communication and backend performance optimization.

I'm pursuing a B.Tech in Computer Engineering while building practical systems across backend engineering, distributed systems, cloud infrastructure, and AI workflows.
