I build AI systems that work in production — and prove they do.
Real-time voice, multi-agent pipelines, retrieval that cites its sources, and the evaluation work that tells you whether a change was an improvement or just a change. Everything below is mine, and it’s all running — scroll and see it, no clicking required.
One minute, in your browser. No sign-up, no install — headphones and a mic, in Chrome.
English Circle
Live
An AI English-conversation tutor for Mexican Spanish speakers
Live voice classes with “Alex,” an AI teacher you actually talk to. Alex replies in natural spoken English in well under a second, understands Mexican slang, corrects you gently without breaking your flow, and sends a personal report after every class.
Type any English line. The Spanish comes back with the subtitle lines that back it up — and two uncited controls under it for comparison.
Subtext
Live
Mexican Spanish subtitles, grounded in evidence and cited line by line
Type an English subtitle line and get it in the Spanish a Mexican subtitler would actually write — with proof. Every reading is retrieved from 103.6 million real subtitle pairs and cites the exact lines it rests on. A guess and a citation are never rendered the same way.

Cinema Pipeline
In progress
An AI pipeline that produces cinematic CDMX shorts
An AI pipeline that produces a complete cinematic world set in Mexico City — original characters, locations, storyboards and short films. Press play: the film, the faces and the streets all came out of the pipeline. No stock, no actors, no camera.
Plug a real guitar into your computer and play along. It listens to what you actually play — detecting your chords in real time — scrolls a rhythm lane, shows finger positions, and the crowd reacts as you nail the changes.
