Session Design
Short, high-intensity runs that fit real mobile usage patterns: quick start, clear stakes, strong payoff.

MOBILE GAMES & APPS, BUILT FOR REAL PEOPLE
I build mobile games with fast iteration, readable combat, and strong game feel — and productivity apps like Roomli that help couples, families, and roommates organize their shared lives. Both designed for iOS and Android.
ABOUT
I'm Mladen Stojanović, a mobile developer building both games and productivity apps. On the games side, I care most about what players feel moment-to-moment: movement response, hit feedback, readable chaos, and progression that keeps each run fresh. On the apps side, I build tools like Roomli that help people manage shared households — shopping, chores, bills, and everyday tasks — with the same mobile-first clarity.
Alongside production work, I prototype VR mechanics to test interaction ideas and bring the best parts back into mobile design where performance and simplicity matter most.

My game workflow is built around practical pillars that match modern mobile play patterns.
