👋 Hi, I'm Sugeng (Wongpinter)

Senior Backend Engineer · 12+ years · Jakarta, Indonesia

I build systems that move data reliably — API gateways, real-time pipelines, change-data-capture, message brokers, CLI tools, and AI agents. Go is my daily driver, and I ship production code in Python, TypeScript, PHP, and Dart.

Currently hacking on GDM (Go download manager) and audiobook-organizer (metadata-driven media library organizer).
