About

Payments, platforms, and observability

Stylized settlement console showing $200M+ daily TPV, 99.9% uptime, and 75% faster settlement time

I'm a backend and platform engineer specializing in high-scale payments infrastructure, observability systems, and distributed systems architecture. I've built settlement systems moving over $200M a day, and cut settlement processing time by 75% with intelligent queuing and scheduling.

I built an RBI-compliant tokenization platform, led Tap & Pay from proof-of-concept to general availability, and introduced full observability stacks — OpenTelemetry with SigNoz, Kafka event marts, and Redis circuit breaker patterns — into high-volume platforms.
