I build reliable backend systems, from payment platforms to proxy infrastructure.

I've built backend systems at tiket.com, flip.id, Ruangguru, and mrscraper.com, improving API performance from over two seconds to under 300ms, introducing clean architecture, and stabilizing production services. I work across Go, Java, PHP, MySQL, PostgreSQL, Redis, and gRPC.

At mrscraper.com, I work on mrproxy routing, SOCKS5 support, Ansible-based configuration, production memory fixes, fleet monitoring, and automated pull-request guardrails. I'm language agnostic and always willing to learn new technologies.
