About Me

I'm a Software Developer at Delhivery's Financial Services team, where I build and scale FinTech microservices handling 100K+ transactions daily. I graduated with a B.Tech in Computer Science from NIT Jamshedpur (2026) and have been shipping production systems since my internship days.

My work spans end-to-end system design — from architecting RBI/GDPR-compliant workflows and integrating banking APIs with mTLS encryption, to building Kafka-based event pipelines and migrating infrastructure across AWS services. I care about writing secure, maintainable code that operates reliably at scale.

Outside of work, you'll find me exploring new technologies, competing in esports, playing table tennis, or building side projects that push my boundaries — like Switch FAANG, a full-stack platform combining AI interviews, recruiter outreach, and a LeetCode-style coding environment.
