Engineering with an eye for detail.

Education: Bachelor of Information Systems, ITB STIKOM Bali; Diploma in Information Management, Politeknik Negeri Bali
Languages: Indonesian (native), English (professional working)

Most of my work sits between a design file and a production codebase. I care about getting that translation right: spacing that matches the spec, states nobody drew, and layouts that hold up at every width, not just the two in the mockup.

Much of what I’ve built replaces a manual process: clinic registrations, warehouse distribution, salon commissions. That means working directly with business owners and end users, running interviews, and asking what a feature is for before deciding how to build it.

I build interfaces as small, typed, reusable components with clear boundaries, and I use AI-assisted development with Claude every day to move faster while keeping code clean, tested and maintainable.
