Java backend developer at Asia-Pacific Bank building resilient banking workflows and payment systems.

At Asia-Pacific Bank (ATB), I engineered fault tolerance for business-critical workflows, using retries, circuit breakers, idempotent processing, and persistent state to help processes complete despite transient failures.

At BPC Group, I architected and built an ISO8583-based ATM transaction gateway from scratch as the sole backend developer in a two-person core project team. It enabled ATM cash withdrawals and deposits, with transaction recovery flows for failed or stuck transactions.

At Selecty on the Alfa-Bank Project, I automated parts of the digital loan acceptance and paperless document generation workflows. Earlier, at VRP Consulting, I developed backend microservices for recruitment and resource-planning products, including a CV-generation service, and at Technoserv Consulting I developed automated regression tests.
