Software Engineer & Designer · Semarang

Javier Fadel portrait

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.

  • Rebuilt Satujiwa platform & editorial CMS with Laravel, React, and booking integrations.
  • Architected Nero, a modular hotel PMS monorepo with Next.js, NestJS, Prisma & Redis.
  • Built internal audit systems & Python data pipelines at UPT Data & Informasi Udinus.
  • Designed production mobile UI, checkout flows, and design systems for PastiPlus.
