Summary
I'm Gio, a Senior Game Developer in Temuco, Chile, working remotely with teams in the US and beyond. I currently work at Game Foundry, an agentic-first casual mobile game studio, and with FabuLingua. I build games in Unity and C# for iOS, Android, WebGL, PC and VR: gameplay, multiplayer, live services, UI, and the editor tools that make teams faster.
I like owning things end to end. At Game Foundry I own the engine and mobile lanes, and I took Vortex Quest from a studio web prototype to a game live on Google Play. At FabuLingua I'm the release owner and a senior engineer on a live kids' language-learning app on iOS, Android and the web, and I built its Echo Hunt mini-game end to end. At Gaxos.AI I was the only engineer on Jigsaw Puzzle AI, a live mobile game where players turn text prompts into puzzles, and I owned gameplay, PlayFab, attribution, IAP and live updates.
My workflow is AI-native, and at Game Foundry it is how the studio works: a builder agent writes the code, an independent reviewer model checks every change, and I make the owner decisions and play-test every build. I also build Unity editor tools that bring AI output into the project as validated content, and keep everything behind tests, code review and on-device profiling. AI makes me faster; it doesn't decide what ships.
