Building systems that scale

I'm a Software Engineer with a focus on backend development. My expertise spans from designing microservices architectures to optimizing database performance for high-traffic applications.

Currently based in Batam, Indonesia, working remotely with teams across Singapore and Jakarta. I specialize in Go and .NET Core, with deep experience in PostgreSQL, Redis, and cloud infrastructure.
