FREELANCE
Senior Unity Developer
To have fun solving concrete and immediate problems I freelance.
I worked mostly on performant and scalabale multiplayer games in mobile and web (i.e. 100 players per room real-time multiplayer arenas with high stability and cost-efficiency) and creative AR/VR solutions (i.e. archviz, google geospatial api, games on Meta Quest).
2019-2021
DISTILL GAMES
Founder / CEO
I had a clear vision for a mobile racing game
so I founded a studio to realize it.
Initially I programmed the selling point - unique car physics,
then produced the game and led the team. The game reached
the top of it's category in retention and engagement.
2017-2019
STARTUPS
Tech / Product
Fueled by desire to work in a small team reaching for the stars again
I turned to local gaming and interactive experience startups in Serbia.
I helped founders secure funding and publishing deals by building compelling prototypes and product / market strategies.
2011-2017
NORDEUS
Tech Lead / Senior Unity Developer
I was lucky to join a great company at a time of growth
and grew together with it. Before I could turn around
I was tech-leading a team running a game with 1M+ daily players,
building a custom UI framework inside Unity,
writing state of the art network replication systems and more.
Besides technical expertise this really formed my professional mindset
around striving for maximum impact, teamwork and personal excellence.
