Alternative website. Same Javi. Fewer quarterly OKRs.
Javi Santana
Cofounder of Tinybird, ex CARTO CTO, Agroguia alumnus, SQL enjoyer, and public advocate for the radical idea that maybe your data pipeline should not need a lunch break.

Professional diagnosis
Based on public traces, newsletters, posts, and a worrying amount of concern for data that nobody asked to store.

Tiny manifesto, unnecessarily efficient
He says pixels build cathedrals, which is cute until you realize the cathedral has a materialized view.
He believes the best data is the data never generated. Brave words from a man with multiple newsletters.
He started with graphics and games, so every backend taking 300ms is judged by a tiny 16ms tribunal.
He will tolerate your stack, but only while quietly wondering why `make`, bash, DuckDB, git, and shame were not enough.

Calibrated seriousness meter
Move the slider. This is science, if you define science very generously and ship it as plain HTML.
Seriousness control
Level 3: says "write it down" with the calm of a man who has already said it 99 times today.

SQL is not a language here. It is a small religious ceremony performed over the wire.
Career, but with helpful annotations
All in good mood. Mostly. Probably. Depends on your query plan.

Selected lore
Raised by 16 milliseconds. Learned graphics, 3D, demos, and the lifelong habit of looking at slow software like it personally owes him money.
Made software for farmers. Profitable, useful, sold eventually. A suspiciously healthy business model for someone later found near startups.
CTO era. Geospatial data, Postgres clusters, maps, and probably enough operational memories to make a normal person take up pottery.
Now: real-time data products. Managed ClickHouse, sub-second SQL APIs, and the ongoing campaign against pipelines that move like paperwork.
Writes about data, LLMs, products, startups, and aging into opinions. The newsletters are where the passive aggression gets a publishing schedule.
Receipts, because he would ask
The jokes are exaggerated, but the ingredients are public and annoyingly consistent.

Change log
Because the prompt asked for one, and because somewhere a technical decision record just smiled.
2026-06-29: Rebuilt `codex.html` as a standalone vanilla HTML/CSS/JS alternative website. Added loud visual system, portrait hero, social links, public-source references, interactive seriousness meter, topic roaster, animated canvas dashboard, career annotations, and the required tracking script.
Note: The previous `codex.html` was not opened, because the local task instructions explicitly allowed reading only `prompt.md` inside this folder.
