"Pixels are humble bricks" is a beautiful sentence, and also a warning that someone is about to build a cathedral instead of a settings page.
javisantana.comWelcome to the Javi Santana Emergency Museum
Officially he is a Tinybird co-founder, ex CARTO CTO, Agroguia founder, software person, data person, map person, and writer of technical things with "low quality philosophy" carefully sprinkled on top.
Unofficially, this is a living exhibit about a man who says he is not very sophisticated and then immediately starts optimizing civilization with a terminal, a spreadsheet, and a suspiciously intense opinion about databases.

Professional Life, But With the Tie Loosened
2000s
Keyboard origin story Started around software, games, graphics, and the noble art of turning "manual work" into "the computer can suffer instead."
Agroguia
GPS for farmers Built useful software for tractors and fields, which is objectively cooler than another dashboard with a gradient.
CARTO
Maps era Helped turn geospatial data into a product, because apparently one kind of data obsession was not enough.
Tinybird
Realtime data Now makes working with analytical data less horrible. This is both a business model and an emotional support service.
Receipts, Kindly Laminated
Bio says co-founder of Tinybird and high performance data processing at scale. Casual. Like putting "moves mountains" under hobbies.
@javisantanaSeven thousand followers, more than five hundred contacts, still somehow writing as if the only reader is a friend who needs a small slap of truth.
linkedin.com/in/javisantanaSoftware, products, startups, and philosophy "tirando a pobre." Finally, thought leadership that admits it arrived in work clothes.
javisantana.substack.comFAIling with data: because after twenty years with data, the brand promise is not victory. It is surviving with better scars.
failingwithdata.substack.com"Technical stuff, startups and low quality philosophy." A sentence so self-aware it should get a board seat.

Passive-Aggressive Quote Dispenser
Not cruel. Just the kind of loving product feedback that arrives wearing steel-toe boots.
Recent Posts, Reclassified as Personality Evidence
Programador
A man goes to the notary and somehow comes back with a meditation on identity, class anxiety, LLMs, and whether he is allowed to call himself a programmer. Normal paperwork.
Recortes 2025
The annual ritual where everyone wonders if the company is doomed and Javi says, gently, maybe read the whole post before panicking professionally.
Comentarios del director
Ryanair, applause, humiliation, possibly product management. The usual holiday brochure for people who debug feelings.
Que viene el lobo
AI companies are coming to change every industry. Please form an orderly queue behind the people who have already changed their LinkedIn headline.
Como uso los LLM
Cursor, terminal tools, tiny HTML apps, and a warning that LLMs are extremely good at being passive-aggressive. Research confirmed by this page.
El prisas
Speed dating, software edition. A leadership philosophy best summarized as: "please show the user the ugly thing before it learns to lie."

Tiny Personality Runtime
- Input One hard problem with too many moving parts.
- Process Make a prototype, talk to users, complain about ceremony, repeat until useful.
- Output A product, a post, and a sentence that makes the team check whether it was a joke.
- Side effect Someone learns why "simple" took three years and two emotional refactors.
Data with feelings
Farmers with GPS
Maps with drama
LLMs with opinions
Social Network Field Notes
On X, the public pose is high performance data processing at scale. On Substack, the mask slips and we get software, products, startups, and charmingly discounted philosophy.
Newsletter Weather
Spanish Substack: thoughtful, direct, allergic to corporate fog. English newsletter: data engineering with the suspicious calm of someone who has seen too much JSON.
LinkedIn Mode
Co-founder. Madrid. Tinybird. Articles about LLMs and documentation. Serious enough for the network, but not so serious that we cannot all hear the terminal humming.
Change Log
- 2026-06-20 Created `codex.html` as a new plain HTML/CSS/JS alternative site. Included tracking script, public social/source links, a cheerful passive-aggressive tone, and no dependencies because Javi already has enough systems to think about.
