about
A Senior Software Development Engineer based in Surabaya, Indonesia. I specialize in frontend architecture, API contract design, and developer tooling. I ship enterprise tools that scale — from 2.3M-row migrations to zero-dependency extensions.
At GDP Labs, I build and maintain critical components for CATAPA, an HR-tech platform serving 15,000+ employees. I've led initiatives across frontend architecture (Angular/NgRx), payment systems (BCA VA/Midtrans), data migration tooling, and compliance features (UU PDP, PMK 168/2023). I also maintain pi-ollama, an open-source extension for the pi coding agent.
Previously at Jojobug in Singapore, I worked across the full stack with Next.js, Node.js, and Firebase. I write about the systems I build on dev.to and ship tools developers actually use.
