I help engineering teams make better architectural decisions — before they become expensive ones.

Architecture · Technical Strategy · Fractional Leadership

With 15+ years designing large-scale cloud systems, I work with CTOs, founders, and engineering leaders as a senior technical partner — on the decisions that compound.

I don't come in to execute a task list. I help you think through the hard upstream problems: cloud migrations, platform design, AI integration into production, and the architectural bets that determine the next three years.

I've built systems that handle millions of daily transactions, led engineering teams through rapid scaling, and created open-source tools used by thousands of teams worldwide. That depth of experience is what I bring to your most critical technical decisions.

How I engage

A small number of focused engagements at a time — each one with my full attention

Architecture Review

You've built something that works — but you're not confident it'll scale, or you're about to make a major bet and want a second opinion. I do a structured deep-dive into your system, identify the load-bearing risks, and give you a clear prioritized picture of what to address.

Good for: pre-scale assessments, pre-launch reviews, platform evaluations

Fractional Architect

You need senior architecture judgment on an ongoing basis — in planning, design reviews, and critical decisions — but you're not ready or willing to make a full-time hire. I embed with your team as a recurring technical partner.

Good for: growth-stage companies navigating scaling decisions

Technical Due Diligence

Before an acquisition, funding round, or major technical dependency, you need a credible and frank assessment of the stack. I evaluate architecture, infrastructure, and technical risk and give you a clear picture — not a rubber stamp.

Good for: investors, acquirers, founders evaluating a technical bet

Platform & Infrastructure Design

You're rebuilding something foundational — a cloud migration, a data platform, a move away from a monolith. I help you design it right before you commit. The decisions made in the first weeks of a rebuild determine the next three years.

Good for: teams facing a major technical inflection point

The situations I'm built for

Systems that need to scale but weren't designed to
Cloud migrations that have to go right the first time
AI integration into real production environments
Architectural decisions ahead of major product bets
Platform rebuilds and structural tech debt at scale
Engineering teams that need senior judgment without a full-time hire

Who this is for

Engineering leaders

Who want a trusted senior voice outside their own org — a thinking partner, not a vendor.

CTOs at scaling companies

Navigating the architectural decisions that compound — the ones that look small now and hurt for years.

Founders

Who want technical confidence before a major infrastructure or AI investment.

Investment and acquisition teams

Who need a credible, independent technical lens before making a bet.

I don't do staff augmentation. I don't do firefighting. I work on the decisions that compound.

Background

Former CTO

Led technology strategy and engineering teams through rapid growth phases — from early-stage architecture decisions to scaled production systems.

Large-scale infrastructure

Designed and operated systems handling millions of daily transactions across energy, mobility, and fintech — including Holaluz, Wallbox, and UserTesting.

Cost & Security at scale

Extensive experience in FinOps, infrastructure cost optimization, and security architecture for cloud-native systems under compliance constraints.

Open source & community

Creator of Ansistrano, the most widely-used Ansible deployment role, with thousands of production deployments worldwide. Founder and organizer of DevOps Barcelona.

Let's talk about what you're building.

If you're facing an architectural decision you're not confident about, or you want a senior technical partner for the road ahead — I'd like to hear about it.
