Message

At PT Kemenangan Indah Makmur Communication, I built an internal Project Management System end to end as a solo full-stack developer, translating event management business processes into a web application. I developed its frontend in React/Next.js and backend in Java Spring Boot.

At Commsult Indonesia, I contributed to the Ontego SDK, developing Flutter components and supporting the Logistic Demo. I also worked on Flutterbook documentation and maintained the SDK through feedback implementation and bug fixes.

For my thesis with Commsult Indonesia, I designed and implemented an offline-first synchronization system for logistics and ERP mobile apps. I built a Flutter client and Java Spring Boot middleware, then tested consistency and performance using Apache JMeter.
