Live KPIs (totally real)
*he still codes at 6AM. make it make sense.
About (the version he'd never write)
Official pose: looking at the ceiling pretending to think something smart
Hi, Javi Santana typing. Builder at the intersection of tech and data. Cofounder of Tinybird — which he now runs as CEO because someone had to push every day and it turns out "empujar todos los días es carísimo a nivel mental."
Find him on Twitter, LinkedIn (the platform he calls full of shamans), or Substack where he writes 3000-word essays about how he doesn't want to be what he is.
Career timeline (passive-aggressive edition)
- ~2000 — Starts as "digitalizador" at a metal company. Hates it so much he automates himself toward freedom.
- 2000s — Programs videojuegos, embedded, backend, frontend. The full caraboli tour.
- ~2010 — Founds Agroguía. Puts tech where nobody put tech. Bloomberg writes about it. Modest exit. Farmers unimpressed.
- 2010s — CTO at CARTO. Converts startup into "referente tecnológico." Also wins "most dysfunctional sales company" award (probably).
- 2020s — Tinybird cofounder. Vibe-codes entire apps in single index.html files. Pays for Grok. Tells you not to use LinkedIn.
- 2025 — Becomes CEO of Tinybird. Employees flinch when he says "Recortes."
- Jan 2026 — Publishes "Programador." Goes to notary. Cannot say the word out loud. Identity crisis achieved.
Things he believes (stolen from /about)
Small & efficient
Builds small things with time, iterating. Except his Substack posts, which are enormous.
"A ojo"
Believes things should be understandable at a glance. His career path is not.
Effort > talent
Creo muchísimo en el esfuerzo. Wakes at 6AM to code ESP32 lap timers. Effort confirmed.
Quality = business plan
Except when he let LebrelBot write passive-aggressive newsletter copy and had to tone it down because LLMs "son especialmente buenos dando donde duele."
Vísteme despacio que tengo prisa
His entire personality in one sentence. Lotus Elise owner. Race track weekends. SQL at dawn.
Terminado y cerrado
Envies physical products. Software is a fractal of never-done. Tightens last bolt on Lotus → peace. Ships Tinybird feature → existential dread.
How Javi uses LLMs (he wrote this, we're just highlighting)
🤖 LebrelBot
AI newsletter editor for Tinybird. Originally instructed to be "passive-aggressive." Had to remove that because the LLM was too good at it. The children and LLMs reflect the worst acts of each one.
🧪 JaviBot (aborted mission)
Trained an LLM on his Slack writing style. It was "bastante cabroncete." Had to shut it down. You're welcome, Tinybird employees.
✍️ index.html everything
His text editor, user journey analyzer, and probably this page's spiritual ancestor: all vibe-coded vanilla HTML apps via Cursor. Bespoke suit vs Zara €119.93.
💳 Pays for Grok
Uses deepsearch on Twitter. Irony not lost on us: you're reading a page made by the thing he subscribes to, mocking him lovingly.
Notario Identity Crisis Simulator™
Inspired by "Programador" (Jan 2026). Type your profession. Hear the verdict.
El notario pregunta: ¿Profesión?
Waiting for your existential input...
A typical Javi weekend (ESP32 edition)
06:00 — Alarm. Large coffee. Nobody else awake. Chef's "cooking for family" time except the family gets nothing.
06:15 — ESP32 data compressor. Kilobyte buffers. Lap timer for race track.
09:00 — Family wakes up. Javi has already confronted mortality via microcontroller constraints.
Saturday PM — Lotus Elise. Circuit Ricardo Tormo. Checks every bolt because software never lets you tighten the last one.
Sunday — Writes Substack post about how he'll never be a programmer again. Publishes anyway.
