About

Hi, I’m Alvin — a developer from Semarang, Indonesia, trying to understand how software actually works. I build apps, break things, fix them, and write about what I learn so my brain doesn’t rot. Most of my work revolves around mobile and full-stack development, but more than anything, I’m just someone who enjoys figuring things out step by step.

This blog is my personal space on the internet — not a portfolio or a place to pretend I know everything, but a public notebook where I share lessons, mistakes, and small discoveries along the way. I’m learning in public, hoping that what I write might someday help someone else who’s also trying to make sense of tech and grow a little every day.
