What I'm looking for

I'm available immediately for freelance or permanent work.

At Playoneer, I shipped five mobile puzzle games, owning gameplay systems, physics-based mechanics and UI from prototype to store release. Box Jam! – 3D Puzzle reached 1M+ downloads and a 4.8/5 rating.

I cut peak memory by about 20% and load time by about 30%, while holding 30 fps on low-end iOS and Android devices. I also integrated monetization and analytics SDKs and supported live content updates after launch.

As a freelance Unity Developer, I was the sole developer of Tossivo, taking a portrait physics puzzle from a public WebGL prototype to signed Android release builds. I split its codebase into nine assemblies and added 440+ automated tests.

My freelance AR and XR work included RAF100 for the Royal Air Force, In the Footsteps of Kings for Fife Tourism, and Allergan BOTOX injection training. Earlier, at Aratog, I built gameplay and progression systems for Astro Lords: Oort Cloud and developed enterprise vessel-tracking software in C++ at Arena Marine.
