JavierFadel
Software Engineer & Designer · Semarang

A professional maker across software engineering, architecture, and design systems. I design interfaces, build them in code, and wire up the workflows around them, from first Figma frame to production build. Lately that includes distributed backends in Go and real-time 3D in WebGL. Based in Semarang.
An AI-augmented workflow with Cursor and Claude Code sits at the core of how I ship. Recent involvements include hotel PMS engines, enterprise systems, and scalable brand infrastructure. I move fast and treat shipping as the only proof that something is real.

- Built internal audit systems & Python data pipelines at UPT Data & Informasi Udinus.
