At CoinSwitch’s Lemonn equities platform, I build backend systems for trading, risk, and portfolio workflows. I shipped Historical P&L end-to-end, from the order-P&L ledger and aggregation tables to BOD processing and frontend APIs.
I delivered PnL Protect from design to production in about three weeks, owning its risk engine, state machine, schema, infrastructure, and live-flow validation. I also built Lemonn’s in-house OMS for positions, holdings, orderbook, and order history, reaching 100% rollout to about 5,300 users.
I work across Go, Java, distributed systems, messaging, and infrastructure to improve correctness and reliability. My work has reduced NOS pod memory by 39%, eliminated deployment-related NATS consumer gaps, and strengthened protections against stale and out-of-order trading updates.
