About

I'm a Fullstack Developer and Systems Architect based in Surabaya, Indonesia, with over 9 years of experience delivering web, mobile, and enterprise systems for startups, agencies, and enterprise clients across Indonesia, Europe, and the US. Most recently, I architected and built a full enterprise ERP from the ground up — spanning finance & accounting, payroll & HR, POS, and field operations — across web, mobile, and desktop, for a multi-entity company.

My stack spans the full spectrum — from crafting pixel-perfect UIs with React and Vue to engineering robust backend systems with Laravel, Node.js, and NestJS, and integrating AI directly into business workflows via the Anthropic API. I care deeply about performance, accessibility, and code quality that teammates actually enjoy working with.

When I'm not shipping features, I'm building open-source tools, experimenting with mobile development in React Native, or deepening my knowledge in WebAssembly and edge computing.
