First I learned to find bugs. Then, not to write them.

Five years in quality assurance across banking and telecom in Panama: core banking, credit cards, AS400, online banking, API services. These days I don't just test them — I build: full-stack web apps and systems that run on language models.

What I've built

  • Torneo Volleyball 2026

    in production

    A seven-team league, 21 games, live all season long. I built it and I tested it.

    53 players · 21 games · zero mismatched scores

    React 18 · TypeScript · Vite · Tailwind CSS · Supabase · PostgreSQL · Playwright · Vercel

    The tournament platform in production: the current round, its games, and the list of teams.

  • Voice queries over Panama's biodiversity data

    runs locally

    Spoken questions in Spanish, turned into SQL by a language model, over open GBIF data. A move to the cloud is on the way.

    51,761 bird sightings · 3 models in a fallback chain

    Python · Flask · MySQL · Whisper · edge-tts · Ollama · Qwen3 · Groq · Gemini

    The interface, with the field for speaking or typing your question.
