Backend engineer at CoinSwitch who built a crypto options quoting engine handling ~10K order operations per second.
IndiaWhat I'm looking for
At CoinSwitch, I built the quoting engine behind an in-house crypto options market maker, handling ~10K order create and cancel operations a second with order receipt to execution under 9ms.
I also designed and led, with one other engineer, the market maker’s six-service Go hedging system. It processes fills across multiple sources and uses NATS JetStream and PostgreSQL to recover state when components fail.
For Lemonn, CoinSwitch’s equities broker, I designed the five-service Go architecture and built the order-management service from its first commit. I later led the eight-engineer team’s migration to a new broker vendor, taking the work from proof of concept to production.
Earlier at CoinSwitch, I authored a Go Config Service that sustained 450K requests per minute, peaking at 1.2M, with a p99.9 of 1.7ms. I’ve also worked on WebSocket event processing, Redis scaling, and payment systems at Astute Giraffe and ImageKit.
