About Me

Developer by trade. Competitor by nature.

I'm Mack — a full-stack software developer with a background you probably won't find on most resumes. Before writing production code I spent years as a professional StarCraft 2 player and streamer, competing as Zerg under the name Mackintac. The same obsession that drove thousands of hours of in-game optimization now drives how I build software. I don't stop until it's right.

I'm addicted to improvement. Whether it's shaving milliseconds off a render, refining a component API, or levelling up a new skill — I bring the same competitive intensity to my work that I brought to the game.
