Devendra Jat

Backend Engineer, Computer Science student at IIIT Nagpur.

I build backend-heavy products with clean APIs, reliable data flows, and production-minded architecture. My work spans payment routing, distributed systems, cloud infrastructure, RAG products, and full-stack applications that are designed to keep working when real users show up.

I am strongest around Node.js, TypeScript, Python, PostgreSQL, Redis, queues, Docker, and practical system design. Alongside product work, I keep a steady DSA and competitive programming practice across LeetCode, CodeChef, Codeforces, and GeeksforGeeks.
