I Rewrote Angular Component Store with Signals - And Cut the Complexity in Half

After 8+ years working with Angular, I thought I had state management figured out. Than I rewrote one of my real-world stores using Signals, because I realize I was mostly managing complexity, not reducing it. The Context Like many Angular developers, I've used NgRx for years. When Compo...

From Level Up to Live Service: How Online Gaming Started Feeling Smaller

There are more games than ever. So why does online gaming feel like it revolves around fewer worlds? Anyone who played online games in Brazil in the 2000s and early 2010s probably remembers a very different feeling. It was not just that there were many games.

They start telling you what you want to hear instead of what's true. And eventually, the person who built them quietly moves on to the next shiny thing. I know th...

Copy-pasted across 50 tests, never catching real edge cases, never feeling like production data. I built FixtureForge to fix this — but along the way, I learned that AI is the wrong tool for most...
