About

I'm Willian (EmechiCode).

I write because it's how I think. It started as notes for myself. Other people found them useful, so I kept going.

For years I've made videos teaching people to code — the kind that meet people where they are, not where the industry assumes they should be. Now I write about the decisions underneath software: the errors that break things, the fixes that hold, and the tradeoffs nobody mentions.

Code that runs isn't the same as code that works for people. That's what I write about.
