About

Hi, I'm Peter John Arao (@pitzzahh online), based in Legazpi, Bicol.

Daily stack is TypeScript + SvelteKit, strong Java underneath, comfortable across REST APIs and Tauri desktops. Right now I am building powertrackr, an electricity usage and payment tracker.

I contribute to open source and enjoy production problems end to end.
