Game design is how my brain works

It's my career goal, and it's also how I spend my free time: every day I'm in an engine, studying a system, or testing a mechanic.

I take apart the mechanics that make games click, then prototype my own versions in Unity and C# so I can judge how a mechanic feels in play, not only how it reads on paper.

Four years of QA automation taught me to hunt edge cases. I bring that to game balance now: playtesting tells me how a game feels, and in Guild of Old Magick a bot-vs-bot simulator runs thousands of matches looking for the broken synergies no one has time to find by hand.

I've designed for screens, tabletops and a live game show. Across all three, the same things hold up: clear choices, real consequences, and a reason to play again.

Prototype first
Ideas are cheap. I build playable versions fast and learn from real play.
Systems thinker
A small change should ripple through connected mechanics in a way players can feel.
Test obsessed
Simulations find the outliers. Playtests tell me how it feels.
Cross-format
Digital games, board games and a live show.

Let's make something fun together

I'm looking for my next role in game design or UI/UX design: somewhere I can obsess over systems, interfaces and player experience.
