Senior Go Engineer at Infinite, building payment orchestration for banking rails, stablecoin networks, FX providers, and compliance services.
VietnamWhat I'm looking for
At Infinite, I lead architecture and delivery of a payment platform integrating banking rails, stablecoin networks, FX providers, and compliance services. I built payment-orchestration and transfer-processing services with idempotent execution, safe retries, and recovery from partial provider failures.
At Vectara, I led the redesign and migration of seven latency-critical ingestion and query components to Go, reducing average response time from about 800 ms to 120–200 ms. I also designed a distributed processing layer serving 1,000–3,000 RPS and about 1.5 million events per day.
At Adyen and Revolut, I designed backend components and payment workflows focused on correctness and failure recovery. I used idempotency, transactional messaging, and explicit failure-state handling to help prevent duplicate financial operations.
Earlier at Andersen Lab, I built and maintained Go services for an integration-heavy platform and participated in migrating production functionality from PHP to Go. I also contributed PrometheusAgent status improvements to Prometheus Operator, including merged PRs #8859 and #8860.
