– Designed and shipped Historical P&L end-to-end, including the order-P&L ledger, aggregation tables, BOD processing and 3 frontend APIs (summary, history and cursor-paginated exit orders); added daily, weekly and monthly aggregation with rerun-safe backfills. – Delivered PnL Protect from design to production in about 3 weeks, owning the risk engine, NOS consumer, arm API, state machine, schema and infrastructure; validated the live flow against strategy rules before rollout. – Reduced peak NOS pod memory from 1.88 GiB to 1.15 GiB (39% reduction) and equalized usage across 3 production pods by moving to headless gRPC with round-robin load balancing. – Root-caused a Kambala SDK memory leak that grew adapter RSS from about 50 MB to 1 GB; profiled the native heap with jemalloc/jeprof and isolated 87.7% of the growth to the Noren SDK before raising a reproducible vendor defect. – Eliminated 30s+ NATS consumer gaps during deployments and fixed stale trading-state races using m-sequence guards and monotonic DB writes; also built AI-assisted P0/P1 alert triage across 8+ services.

– Built and rolled out Lemonn’s in-house Order Management System (OMS) for positions, holdings, orderbook and order history, replacing broker APIs as the primary source of truth and reaching 100% rollout to about 5,300 users. – Designed the OMS rollout with validation, broker fallback and Redis-controlled staged rollout (0/10/20/100%), plus runtime kill switches and exclusion lists for users with data mismatches. – Improved OMS correctness through history tables, FIFO cost-basis fixes, modify-order state handling and m-sequence-number protection against out-of-order socket/sync updates; also ran a 90-minute OMS KT for the wider engineering team. – Took ownership of the ODIN-to-Kambala broker migration across order management, portfolio and the Go/CGO vendor adapter, covering BOD validation, order/trade socket correctness and post-go-live RCA actions.
