Engineer-minded. Player-obsessed.
For over five years I have shipped games end to end in Unity. I design gameplay systems, wire up real time multiplayer, build live PlayFab backends and squeeze every frame out of mobile and VR hardware. I started young, and my first published Android game passed 11,000 downloads back in 2017.
Since then I have self-published several mobile games, contributed to Football Manager 2026 and delivered 50+ projects for studios and founders worldwide, with a 100% Job Success score and Top Rated Plus status on Upwork. I'm just as comfortable owning a PlayFab backend as polishing a shader, and I'm always looking for the next ambitious title to bring to launch.
