Ratri Risyanto

Automation and application developer. I build tools that take over the repetitive work — and lately, full-stack apps on top of that.

Live demo: SiJaga Sungai — AI platform for identifying invasive fish species in Indonesian rivers. Runs on Google Cloud Run; open it and try it, no setup needed.

What I work on

Spreadsheet automation. Years of building Excel/VBA systems for manufacturing, logistics and distribution businesses — inventory, payroll, receivables, production scheduling, traceability, POS. The kind of work where a process that took a person half a day becomes a button.

Web & mobile applications. React + TypeScript on the front, Supabase or Firebase on the back, Kotlin/Jetpack Compose when it needs to be a native Android app.
