Message

At RoaminRabbit, I designed, developed, and maintained backend APIs for Android and iOS apps, web platforms, and self-service kiosks. I also contributed to system design, backend architecture, and database optimization.

At Alodokter, I combined architectural design with hands-on development, working on microservices and distributed systems. I also led proof-of-concept initiatives and helped establish engineering practices.

Earlier, I developed an ERP system at Ukirama and designed ETL processes, reports, and dashboards at Juke Solusi Teknologi. I bring experience across backend and full-stack development, API engineering, and business intelligence.
