About Me

A Bit About Me

I'm Boy, a full-stack developer from Batam with a Master's in Computer Science. Over the last 6 years I've gone from keeping university exam systems running at 99.9% reliability, to building logistics dashboards, to architecting a warehouse management system end to end.

Outside the day job I spend most of my time around data and finance: market dashboards, stock research tools, and small utilities that solve one problem well. My philosophy is simple: good tools, better days. The best software gets out of your way and loads fast.

This site is my corner of the internet: part portfolio, part public notebook. Everything here is a work in progress, including me.
