Gameplay, live services, mobile releases and editor tools in Unity/C#, built at an agentic-first studio with AI coding agents and reviewed like it matters. Temuco, Chile · Remote · Chile time (UTC−4 / UTC−3)

Sanitized reconstruction of a Unity editor-tool session, not a recording. Paths and prompts are simplified.
Three projects where I built the core systems, from gameplay to the tools around it. Cover art is interim; gameplay captures replace it as they are cleared.
Took a studio web prototype to a live Google Play game: a 101-level campaign, cloud save and a global leaderboard, and a release pipeline with thousands of tests behind every build.
Release owner and senior engineer on a live kids' language-learning app on iOS, Android and the web: built the Echo Hunt mini-game, moved subscriptions to Adapty and shipped versions 2.0.16 to 2.2.0.
Only engineer on a live mobile game where players turn text prompts into puzzles: gameplay, PlayFab, Adjust/AppsFlyer, IAP pricing and live updates.
Shipped titles, prototypes and client work since 2019.
Internal live-services SDK behind every studio Unity game: providers behind interfaces, an offline local provider, and editor tools that show live player data.
Seven Unity mobile games built by a builder/reviewer pair of AI coding agents, to measure how fast they can ship; I make the calls and play-test every build.
Ported core systems from C++ to C# on Bethesda's Fallout Shelter without changing gameplay behavior.
Real-time Photon multiplayer brawler (solo and team matches, leaderboards) with PlayFab live ops, launched on iOS and Android in 2023.
Web-playable arcade shooter that showcased in-game AI asset generation; I worked on gameplay, PlayFab progression and analytics.
Custom racing camera and rendering optimization for live races on real San Diego streets.
Gameplay features for an open-world Solana game where NFT ownership is part of the core loop.
Prototyped a 3v3 real-time hero battler and its core loop from design specs.
VR and PC training simulators built from scratch for enterprise clients, connected to client backend data.
At Game Foundry, an agentic-first studio, humans choose what deserves investment and AI coding agents turn that intent into playable builds. I write the spec, make the owner decisions, and stay hands-on wherever game feel, architecture or player data are involved.
Agents never work on main · nothing merges unreviewed
A builder agent implements each milestone on a branch and an independent reviewer model reviews every change. At Game Foundry I built the ticket to branch to PR flow around that: a PR-gate CI, automated cross-model review with risk-tiered auto-merge, and a local review fallback.
Seven Unity mobile games, built to measure how fast an agent pair can ship. Each has a design doc with numbered owner decisions, a milestone plan with estimates, a live time log and a defect ledger. The first game's milestones M0 to M9 took about 33 to 43 hours of measured agent time against a plan estimate of 65.5 agent-days; the log treats that as a lower bound, reconstructed from timestamps.
Agents run Unity headless or control a live editor through the CLI, profile through it, deliver builds to devices over adb and record gameplay clips headlessly, with watchdogs on long runs. A shared harness generated into each game keeps every game on the same engineering rules.
AI output only counts once it is validated inside Unity. A licensed 3D asset pipeline converted 798 models from FBX to GLB with zero failures, exports Unity prefabs and catalogues about 7,000 asset entries. At FabuLingua, AI voice generation runs inside a Unity editor tool that stamps provenance on every clip and transcodes it in the editor, and build validators fail a release that is missing its Addressables or localization content.
At FabuLingua, visual features start in an interactive HTML prototype lab, and a direction is chosen there before any Unity work. Agents then check their own changes in the live editor: they enter Play mode, capture screenshots at device resolutions and read the console, under hard rules: no code edits during Play and no saving open scenes.
I have shipped games where AI is part of the product: Jigsaw Puzzle AI turns a player's text prompt into puzzle art at runtime.
Agents never work on main. Every change passes the PR gate and a review by a second model, and only low-risk changes merge on their own. I make the design calls and play-test every build, performance changes get profiled on device, and generated content for kids' products goes through human review.
AI makes me faster; it doesn't decide what ships.
Overlapping bars are parallel engagements. Each role links to the projects it produced.
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.
