I've built and maintained large-scale digital platforms for Telkomsel and Siloam Hospitals, improving API performance, production stability, and critical hospital workflows.
At PT. Bithealth, I optimized database queries and resolved N+1 issues to improve API response times by up to 70%. I also refactored legacy systems, strengthened logging and monitoring, and delivered backend and frontend enhancements for Siloam Mobility.
At PT. Phincon, I led 10 engineers delivering high-performance services across 30+ Telkomsel applications, achieving 100% SLA compliance in non-functional testing. I also built scalable APIs and frontend modules for MyTelkomsel Web, App, and Lite, with automated tests exceeding 80% coverage.
Earlier at PT. eGoGo Hub Indonesia, I developed real-time multi-marketplace, ERP, e-commerce, and logistics platforms, including integrations across seven major marketplaces.
