At Dealls, I co-designed a push-based payroll data flow that cut processing for 1,000–2,000 employees from over 20 minutes to under one minute. I also reduced attendance-query p95 from 10 seconds to 0.5 seconds.
I designed the database schema and backend for an overtime module with a two-engineer implementation, and investigated production incidents involving blocked queries, PostgreSQL WAL growth, and service crash loops.
At PT GoTo Gojek Tokopedia Tbk, I designed configurable insurance eligibility logic for services handling approximately 600 RPS in normal traffic and 1,000 RPS during promotions. I delivered a zero-downtime migration using staged canary releases and production monitoring.
Across my other work, I built SSO and finance APIs at PT Ganeshcom Mitra Solusi Digital and Node.js REST APIs at Infineeds Indonesia. On Claw and Tide, I designed Go and PostgreSQL backends that handled approximately 200 requests per second during a sales event.
