Peter John Arao

Full-Stack Developer — Bicol, Philippines

Since 2020 I’ve worked across Java, modern frontend stacks, and desktop tooling. I design and implement responsive, high‑performance user interfaces and server APIs, and I’ve contributed to HR systems, utility apps (powertrackr), and several marketing sites. My priorities are security, maintainability, clear APIs, and shipping value — from database design and ORM integration to selecting the right deployment and delivery approach based on project requirements. I contribute to open‑source and enjoy solving production problems end‑to‑end.

About

Hi, I'm Peter John Arao — full-stack developer based in Bicol, Philippines. You can find me as @pitzzahh online.

I write clean, maintainable code and care about good developer experience. My daily stack is TypeScript + SvelteKit + modern web, but I also have strong Java knowledge (not currently used at work, will pursue this more) and I'm comfortable across the stack — REST APIs, desktop apps (Tauri), you name it.

Right now building powertrackr — an electricity usage & payment tracker.
