At PT. Infomedia Nusantara, I contribute to the rewrite of Tendering SPSE services from Java to Golang while preserving existing business functionality. I also develop and maintain backend services for LKPP's electronic procurement platform.
For Telkom Indonesia's GovTech Procurement project, I develop GraphQL and REST APIs that support integration and data access across the procurement platform.
At PT. Lunaria Annua Teknologi (Koinworks), I architected and led scalable, event-driven microservices for core financial systems. I led the implementation of a loan repayment service and introduced distributed tracing across backend services.
Earlier at Koinworks, I improved API performance by 35–40% through query optimization, indexing, and data type tuning. At PT. Digital Siber Indonesia, I developed a CMS platform and backend APIs for mobile application features.
