THE COMPLETE INDEX · 2016 — 2026

Everything I've
worked on.

The hub shows the work that argues for itself. This is the rest of it — every prototype, every jam, every tool, including the ones that went nowhere.

Games & jams

DESIGN + PROGRAMMING UNLESS NOTED

Recurring collaborator: Santi — “Arcadehead” (art), credited alongside me on six of the games below, from 2019 to 2026. Music and sound effects in the jam games come from third-party libraries and are not my work.

2026

Rush Fighter

2D beat 'em up built on parry timing. JaénJam II. Godot 4 with C#, exported to the web through WebAssembly — a path Godot 4 does not officially support, documented in the repo. Programming, in a team of four.

2026

mAscAr

Narrative horror / interactive fiction, advanced one key at a time. MálagaJam Weekend 20. Godot with GDScript. Same four-person team as Rush Fighter.

2024

Point of No Return 🏆 2ND OF 55

Space exploration where the universe keeps expanding around you. Unity Jam 2024 (Tooling.gg), a jam with cash prizes: 2nd overall, 2nd in theme interpretation, 4th in mechanics. Five days, two people.

2024

The Precise Hero 🏆 4TH GAMEPLAY OF 78

Precision platformer about a hero who falls asleep mid-jump. // TODO Game Jam 2024, three days: 4th in gameplay, 8th in originality, 10th overall. Its itch page keeps a speedrun leaderboard with real player times.

2024

Feather Fallout

Two-colour tower defense where turrets swap colour and target on command. Built in two weeks taking the theme and the two-colour constraint of 1 bit Jam #4 as a design restriction — it was not submitted to the jam. Economy balanced as a written document first.

2022

G!RO 🏆 MOST ENJOYABLE GAME

One-button arcade with a ship that never stops rotating. Audience award at Fun&Serious Bilbao 2022 and nominated Best Retro Game. Made by the Negone collective — started with four, finished by two, with me as lead programmer and designer.

2019

FADE 🏆 3RD PRIZE

Serious game about Alzheimer's. Hackathon Telefónica 2019, serious games and gamification category, 48 hours. One of two programmers in a team of five. No build was published — the record is the video.

SOLO

Talassophobia

Horror piece about waking up alone in the middle of the ocean. Mini Jam 159, two days, under an “as small as possible” constraint. Solo developer.

Production & studio work

PAID WORK · YBVR · LURTIS AI · ISOSTOPY

2024 — NOW

Xtadium — YBVR

Meta's featured immersive sports app on Quest, built in partnership with Meta. I own spatial UI positioning, notifications, onboarding, localization and the spin-off architecture, and I lead the device-agnostic architecture effort. Full breakdown of what is mine and what was the team's in the case study.

2025

Xtadium Music · CultVRe

Two separate Meta Store releases shipped from the Xtadium codebase through the feature-flag system I built. Immersive concerts, and culture and heritage.

MUSIC ↗ · CULTVRE ↗

2025

NASCAR 3D Tabletop

Interactive race miniature driven by real telemetry, 100+ cars synced frame-accurate to live and recorded video alike, with its live leaderboard. Fully developed as an internal R&D build — never shipped to users, never used in a live event.

2022 — 2024

ZPLN — Lurtis AI

Space strategy-shooter with pinball bouncing, published on Google Play. Mechanics and environments, plus an Angular / TypeScript / Firebase management dashboard and an early multiplayer mode.

GOOGLE PLAY ↗

2023 — 2024

Lorak — Lurtis AI

Transmedia RPG: the same character carried across tabletop sessions, a virtual tabletop and a mobile game. I defined and helped design the inventory system, and prototyped the core loop — party management and expeditions into procedural scenarios. Funding ended before release.

ABOUT ↗

2023 — 2024

Kumal — Lurtis AI

A Unity tool for creating and co-designing 3D scenarios, from single rooms to whole worlds, meant to buy design time back for narrative and gameplay. Publicly funded R&D (CDTI). I worked on the tool itself, not just as its user.

2022 — 2023

Private Unity & programming tutor

Three second-year students on the same game development programme I had just finished, tutored through the school year in the programming subject. All three passed.

2021

Classroom 2060 — Lurtis AI

Serious game teaching recent history to teenagers in the classroom. Unity development, during an internship.

ABOUT ↗

2020

Pre-Trip Inspection — Isostopy

Tools & utilities

THINGS BUILT SO THE NEXT PROJECT STARTS FASTER

UPM

Unity Utilities

My own Unity package of components and extensions, reused across personal projects and jams.

PRIVATE REPO

UNITY

URP jam template

A base project with the packages I always end up needing, so a jam starts on code instead of configuration.

PRIVATE REPO

C++

Breakout on Android Studio

Breakout written natively in C++ for Android, without an engine.

CODE ↗

PYTHON

Python × Notion

Utilities to read and modify Notion databases through its API.

PRIVATE REPO

Web prototypes

SELF-INITIATED · NOT IN PRODUCTION

Built on my own initiative for real businesses I know personally, and pitched to them — there was interest, but neither went into production. They were not commissioned. Both were built with AI assistance: I brought the requirements, use cases and architecture, reviewed and iterated; the code was written by Claude Code. The repositories stay private for that reason.

NEXT.JS

Liga VCM — Voleibol Centro Madrid

League management: 34 teams across three divisions, results, standings and court booking across five sports centres. It came out of a league I actually play in.

4 PIECES

Kylo Ren lightsaber · Gaming room · Battle droid · E-5 Blaster
