Game Designer, Rio de Janeiro

Hi, I'm Mark. I design gameplay systems, progression, and Live Ops for mobile games.

Over the past 5+ years I've worked across systems and combat design, progression and economy, and Live Ops on mobile F2P titles. Currently designing Card Guardians at Tapps Games. Previously at Pixodust, Futster, Campus Studio, and Prisma Game Lab.

About

I'm a game designer based in Rio de Janeiro with 5+ years of experience across mobile F2P and live-service titles. I move comfortably between disciplines: combat and systems design, progression and difficulty balancing, economy design, and Live Ops content that keeps games engaging long after launch.

Day to day, that means prototyping mechanics, tuning numbers in spreadsheets and in-engine, running A/B tests, and reading player data to figure out what's working and what isn't, then implementing and tuning the fix directly in Unity alongside engineering, art, UX, and product. I've also explored gameplay prototyping in Unreal Engine 5 through personal projects.

I'm a Computer Science graduate from PUC-Rio, where I'm now pursuing a postgraduate degree in Human-Computer Interaction & User Experience (UX), expected in 2027. Outside my day job, I make time for game jams and indie prototypes with Prisma Game Lab, including an SBGames 2021 finalist.
