I build the boring parts
extremely well.

Senior / staff software engineer, 17 years in. Fintech, e-commerce and SaaS — mostly the layer nobody sees until it breaks — and lately, AI agents on top of it. Based in Spain, working in English.

Hello, in person

Shorter than reading this page: who I am, how I work, and what I'm looking for next. Subtitled, so it works on mute.

Where I'm most useful

Designing the system

Service boundaries, events, failure modes. I draw it before I build it — and keep the drawing honest afterwards.

Leading without leaving the code

Seven engineers at Dewais, a 30-person org at EPAM. Decomposition, estimates, reviews — plus my own pull requests.

Making slow things fast

An import path handling 50,000 records a transaction, 70% faster. Queues that stopped losing work quietly.

Putting AI agents to work

Building agents with LangGraph and LangChain — tool use, retrieval, and the guardrails that keep them predictable in production.
