Work
A curated selection of backend systems and software engineering projects.
RelayBox
Transactional Outbox Pattern in Go — guaranteed at-least-once Kafka delivery with built-in idempotency. Benchmarked at 200 req/s relay and consumer throughput with 15μs average processing latency and zero failed events under continuous load.
Loadbalancer (L4)
Zero-dependency Layer 4 TCP/UDP load balancer in pure Go stdlib. Benchmarked at 1,185 RPS under 1,000 concurrent connections over 10 minutes — 825,350 total requests with zero errors.

Backend Engineer.
Building production systems
at Jio Platforms since 2023.
Backend Engineer with 2+ years of experience delivering high-throughput, zero-downtime enterprise systems at Jio Platforms. I specialize in Node.js microservices, distributed data stores, and complex RBAC/ABAC security models — with a proven track record of eliminating manual workflows, enforcing zero security violations in production, and building execution engines that sustain sub-second latency at 10,000+ daily transactions across services supporting 5,000+ users. On the side, I build in Go to sharpen my systems instincts: a zero-dependency L4 load balancer benchmarked at 1,185 RPS, and RelayBox — a Kafka Transactional Outbox implementation sustaining 200 req/s with 15μs average processing latency. When I'm away from the terminal, you'll likely find me traveling or at an EDM festival.
