Freelance Unity Developer

Gameplay Systems, Tools, and Technical Workflows for Unity Projects

I help studios and indie teams build gameplay systems, editor tooling, UI workflows, optimisation solutions, and production-ready Unity features.

Who I Am

I am a Unity / C# developer specialising in gameplay systems, tools programming, and technical workflows. I have professional experience working on commercial mobile titles and building scalable Unity systems for production teams.

Previously I worked as a Gameplay Programmer at Halfbrick Studios, contributing to live mobile titles, optimising performance, rebuilding gameplay systems, and supporting cross-platform releases.

I now run DangryGames, where I develop indie projects and provide freelance Unity development, tools programming, and technical consulting for studios and indie teams.

I am currently developing Space Cat Survivors, a roguelite space-mining game.
