Now
General Manager, AI Business, PT Fast Beauty Indonesia (May 2026 – present). Public branding remains programmer and software architect. This page lists systems I built, not employers.

What this range says
The through-line is not one framework. It is building practical systems across layers:
- Laravel/Vue SaaS projects
- AI operations with verification gates
- product documentation and automation
- web publishing systems
- Windows desktop utilities and hardware-adjacent testers
I do not ask only whether a tool demos well. I ask whether it can survive maintenance, handoff, local constraints, and the boring parts after launch.
