Lead Backend Engineer at CargoNect who cut freight-matching query latency by 45% and eliminated peak-hour timeouts.

At CargoNect, I rebuilt PostgreSQL indexes around real query plans and added Redis caching for freight-route lookups, cutting p95 query latency by about 45% and eliminating peak-hour timeouts. I also engineered the freight-matching engine and built an OpenAI pipeline that turns incoming emails into structured freight details and draft quotation requests.

At Fudy, I architected an order state machine across microservices and built a Stripe payment service with idempotent webhook handling. I also founded VisitAdd, a live multi-tenant gym automation SaaS with paying clients, and built backend systems for logistics, healthtech, and social discovery.
