What I'm looking for

I’m seeking roles where I can lead engineering efforts on Unity games, ship player-focused experiences, work in Agile teams, and apply web/mobile skills to live services and growth.

I’m a Unity-focused game developer with strong C# skills and a track record of shipping projects, including the Steam release Trials of Randoom. I excel at building gameplay systems, integrating live services, and improving performance and stability.

I’ve led small teams and served as both hands-on engineer and technical decision-maker, driving optimizations that cut user error rates and rebuild monetization systems to double revenue. I’m comfortable working in Agile/Scrum environments and using Git for version control.

Beyond core game development I have practical experience with web and mobile technologies (React, React Native, Node.js, Express.js, JavaScript, Python) and have contributed as a full‑stack developer and freelancer on published apps and mobile games.

I’m adaptable from fast game‑jam prototyping to longer production cycles, skilled at integrating services like Firebase and PlayFab, and interested in roles where I can continue shipping player-focused experiences while leveraging web/mobile capabilities.
