AI agents that do real work
Almirant is the lab: orchestration, evals and cost per token. Almost everything I learn there ends up on the blog.

Hypothesis, experiment, measure.
I'm F. Javier Pedrosa, PhD, and that line above is the scientific method applied to software and business. I'm also published academically as Francisco Javier Pedrosa Ruiz, and @fjpedrosa on GitHub. Same person. What I kept from the physics PhD is the best part: the method. I've spent 15 years applying it to products in production and today, as Head of AI Agent, to AI agent systems. Evenings go to my own projects; the latest is Almirant. Still allergic to buzzwords.

An engineering degree, a PhD, fifteen years of product and a change of subject
2011
Industrial Engineering degree, Industrial Electronics, Universidad de Cádiz. Final-year project: a microcontroller-based electrical energy meter.
2017
PhD in Condensed Matter Physics and Nanotechnology, Universidad Autónoma de Madrid. Thesis: Towards ferrite based rare-earth free permanent magnets (PDF).
15+ years
Product, from whiteboard to production. Startups, growing teams and plenty of opinions about microservices nobody needed. From Málaga.
Now
Head of AI Agent by day. Evenings go to Almirant, Flatzer, Anotea and whatever comes next. More personal every time, and more of it written up on the blog.
What I keep from the PhD isn't the magnets. It's the habit of not trusting a nice result until it repeats. That is exactly what I do with agents: measure, evaluate, measure again.
// what I'm up to
What keeps me busy these days
This is not a list of services. It's the list of things my evenings and the odd weekend go into, in case we overlap on any of them.
Writing up what I try
Experiments with Codex, Claude Code and Cursor, told with numbers rather than opinions. Sometimes they go wrong; I write that up too.
Weekend projects
Flatzer, Anotea, Medianonymizer. Some with users, some in the drawer. Every one taught me something I didn't know.
Arguing about architecture
I have opinions about microservices nobody needed and about saying no in time. If you disagree, even better: that's a conversation.
