About
I'm a Full Stack Developer based in Jawa Tengah, Indonesia with 2+ years of experience building web applications, SaaS platforms, and enterprise systems that people actually use every day.
Most of my work revolves around POS systems, multi-tenant SaaS products, and healthcare information systems — handling everything from database architecture and RESTful API design to responsive frontends. I've integrated third-party APIs ranging from thermal printers to national health platforms like BPJS V-Claim and SATUSEHAT.
I work across the full stack: Laravel, Next.js, Go, TypeScript, Vue, Angular, and PostgreSQL are my daily tools. I care about architecture that scales without overcomplicating things — and code the next developer can actually understand.
