Sugeng Supriyadi (wongpinter)
Senior Backend & Mobile Engineer · 12+ Years Experience · Jakarta, Indonesia
I build systems that move data reliably — API gateways, real-time pipelines, change-data-capture (CDC), message brokers, CLI tools, and native Android applications. Go is my daily driver, and I ship production systems in Python, TypeScript, and Kotlin.
