About

I started my career building desktop healthcare systems in C# at Ratnasari Sehat, which taught me that software failures have real human consequences. That philosophy still drives how I build: performance-first, security-aware, always maintainable.

These days I'm deep in distributed backends, DevOps automation, and experimenting with AI/ML integrations at Codelabs Indonesia. I believe the best engineers write code their future selves can still read at 2 AM.
