About.

Backend Software Engineer with 10+ years building scalable, performant, and secure web applications — Golang, PHP, and Node.js, from RESTful and GraphQL APIs to third-party integrations and WordPress work.

Systems built from scratch, performance work on systems that already exist, or an integration that has to hold — payment gateways, CRMs, external APIs. Clean code, and engineering practice that survives the handover.

Based in Jakarta, Indonesia. Open to remote freelance work worldwide.
