What I'm looking for

I'm looking for remote or relocation opportunities where I can own full-stack products end-to-end, build reliable production systems, and apply AI/LLM integrations to practical business problems.

At PT JST Indonesia, I own mission-critical systems end-to-end for a 600+ employee manufacturing operation. I solely maintain 17 factory-floor mobile apps and 5+ internal platforms under zero-downtime constraints.

I built a General Affairs automation system that cut administrative overhead by 90%, plus an HRMS, LMS, and payroll platform that automated scheduling and certification tracking. I also shipped SIGA fire-safety monitoring and a real-time AIoT dashboard with 1-second machine telemetry.

I've delivered freelance SaaS, web, and Web3 products from scoping through deployment, and previously reduced product defects by 80% at eFishery through systematic pre-release QA. I work independently across React, Laravel, mobile development, databases, cloud infrastructure, and AI/LLM integrations.
