John Kevin Umali

Full Stack Engineer atOrbital

I build web applications, APIs, and cloud systems. My work spans payment platforms, developer tools, and the occasional side project.

Cabuyao, Laguna, Philippines

A little about me

I’m Kevin, an engineer based in Laguna. I care about how a system works behind the interface, and whether it’s useful to the people using it.

Away from code, I’m usually playing video games, reading light novels, or trying a new food spot.

Selected work

Useful tools, side projects, and the thinking behind them.

Creator & developer

repyy

A closer look at unfamiliar code, before you run it.

I built repyy after seeing stories about malicious take-home assignments. It scans source and setup scripts without executing the target, then produces a local HTML report to review.
