The Approach

Most companies know AI matters. Few know how to actually ship with it. The gap isn't ambition — it's execution. I close that gap as a hands-on practitioner, not a strategist with a deck.

Practitioner, not advisor

I've run multi-agent coding sessions in production, built eval frameworks from scratch, and driven measurable CVR improvements through agentic workflows — at companies handling significant scale. I bring that same hands-on rigour to every engagement.

End-to-end, not point solutions

From concept validation to shipped MVP, from team workflow redesign to org-wide AI adoption — I work across the full arc. You get a partner who understands both the code and the people writing it, and can operate at both levels simultaneously.

AI Adoption & Transformation

For CTOs · VPs of Engineering

Your engineering org needs to work the way the best AI-native teams work. I design and implement the workflows, protocols, and quality gates — then embed long enough to make sure they stick.

Fractional AI-Augmented Leadership

For Series A–B Startups

Fractional technical leadership embedded into your existing team. I bring agentic workflows, eval design, and hands-on execution to teams that are building fast but need senior guidance to build well.

Concept → Prototype → MVP

For Founders · Product Leaders

You have an idea. I compress what used to take months into weeks — using AI-augmented development from day one, with the EM judgment to know what an MVP actually needs vs. what feels necessary but isn't.

Vibe Code → Production

For Builders · Indie Founders · Creators

You built something real with Lovable, Bolt, v0, or another AI tool. Now it needs to survive contact with real users. I audit your codebase, harden it for production, add the observability and deployment infrastructure you're missing — and augment it with AI where it counts.

Who I Am

I'm a software engineer and engineering manager focused on AI, based in Spain. Over the past decade I've led high-performing product engineering teams at Amazon, Shopify, HubSpot, Mastercard, and MoonPay — spanning fintech, e-commerce, mobile, and developer tooling.

I was an early adopter of agentic development — not as a concept, but as a daily practice. I designed multi-agent coding sessions, built evaluation pipelines, and drove org-wide AI adoption that delivered measurable outcomes at scale.

I operate at the intersection of technical depth, product thinking, and people leadership. I've launched zero-to-one products that got adopted company-wide, rebuilt legacy architectures serving large-scale platforms, and coached engineering managers into autonomous leaders. Now I bring that compound experience to companies navigating the AI transition.

LET'STALK.

If you're navigating the gap between AI ambition and real engineering outcomes — whether that's transforming a team, shipping an MVP, or getting your vibe-coded app to production — I'd like to hear about it.
