About
I bridge product and engineering, and I build the thing myself.
I’m a Senior Product Manager. Ten years building digital products, most recently at BigBuy, a B2B2C wholesale marketplace with 400,000+ products and 200+ marketplace integrations.
The last stretch has been AI, and specifically the unglamorous half of it: not the demo, but what it takes to put a system in front of paying customers and keep it honest. Evaluation suites. Deploy gates on model quality. Guardrails. Escalation that hands a person the context instead of the raw thread.
I’m technically literate rather than an engineer, and I’m precise about the difference. I design the architecture, own the prompts and the knowledge base, and set the quality bar. Engineers own the platform and the implementation. That split is in every case study on this site, because a claim that doesn’t survive the first follow-up question isn’t worth making.
I work remotely from Spain, in English and Spanish, and I build things myself: client websites, chatbots, voice bots, workflow automations. The tooling I built for my own product team is one of the cases here.
How I work
- Spec-driven
- Ambiguity gets resolved in the document, not in the sprint.
- Outcomes over output
- A shipped feature nobody opens is not a result, and I'd rather say so.
- Build to learn
- Prototype it, put it in front of a real user, then commit engineering time.
- Honest numbers
- Every figure on this site has a baseline and a scope, or it doesn't appear.
Questions I get asked
- Do you write code?
- Enough to be useful and not enough to call myself an engineer. APIs, JSON, Git, TypeScript, some Python. I prototype, I read what engineering ships, and I write specifications precise enough to build from. I don't pretend the last part is the same as the first.
- What does 'AI Product Manager' actually mean here?
- That I've shipped AI systems into production and owned the parts that decide whether they survive there: the evaluation practice, the quality gate, the knowledge base, the escalation design. Not that I trained a model.
- Remote?
- Yes, fully. Based in Spain, working across European and US time zones.
