About Me

Hey, I'm Tatang — a backend developer who loves building reliable systems that don't crumble when things scale. I've been doing this for almost five years now, mostly using Go, TypeScript, PHP, and SQL. I enjoy designing clean, maintainable backends that make developers' lives easier and systems faster. I've worked on stuff like membership systems, logistics platforms, and flash-sale backends — the kind of things that quietly keep everything running. I also mentor through Kampus Merdeka because helping others grow reminds me why I started doing this in the first place.
