My own site
You're on it. Ask the robot about my work, in English or Spanish, and it answers out loud while a board behind it draws whatever it's talking about.
Experiments and smaller builds
67 experiments since 2021. This is where I break things first.
Also
A robot that pitches me. A game that reached 80,000 players.
Valley of Guardians
Browser game · as part of the team
A React and Supabase browser game that reached about 80,000 users, and about 10,000 kept coming back. As part of the team I built product screens and the daily reset that runs under all of them.
Products, end to end
Four products. Each one had a hard part.
Jarre
Paste a YouTube video, get a course: lessons, quizzes, spaced repetition, and a tutor you talk to out loud.
Next.js · Supabase
Sweepy
Gmail, sorted by AI from a Chrome extension. A sender cache, a backup model when the first one fails, and five minutes to undo anything. It is your inbox, after all.
Next.js · Manifest V3 · Claude · GPT
e-translator
Technical manuals into other languages, layout intact. The sample PDF looked fine and lied: its text layer was garbage. A pilot in about a day, the test document from about 5 minutes to about 1, and a five-star review.
Python · Docling · Tesseract · PyMuPDF
Flópiti
Multiplayer 2D in the browser, on terrain you blow apart. The server simulates at 60 Hz and has the last word; the browser predicts and corrects, on 8 to 16 KB/s per player.
React · Phaser · Node · uWebSockets
In 3D and in the browser
Hobbs Cafe
A city block, lit and baked in Blender, running in a browser tab.
React Three Fiber · Blender lightmaps · glTF
Gatonomía
Shared expenses for a couple. Quick capture, a monthly view, Google login. Live.
React · Convex Auth · Tailwind
Studio
A Blender scene that moves to the music.
Stickers
Decals that stick to curved surfaces, like the real thing.
Wormhole Tunnel
A tunnel made of nothing but GLSL noise and displacement.
Chicken Road
A chicken versus traffic, in 3D, in your browser. Live.
React Three Fiber · Zustand

Freelance
Websites, apps and 3D experiences for agencies, startups and businesses, ideally for the long run. Doubland started as an Upwork contract; today it's a direct one.
Full-time, remote
I'm looking for a full-time remote role at a creative, cutting-edge company that sweats design and detail: AI, 3D worlds or digital twins.
