I help founders and CTOs make better technical decisions — before they become expensive ones.

Architecture · Cloud Strategy · AI Integration · Fractional Leadership

With 15+ years designing large-scale cloud systems, I've been CTO at Holaluz — scaling a team from 8 to 30 people while the business grew to €14M/month — and spent years helping companies across Europe and the US untangle infrastructure that had quietly become a liability.

Today I focus on two things: helping teams figure out where AI actually moves the needle — in refactors, in legacy modernization, in the business itself — and helping CTOs and engineering leaders make the infrastructure calls that are hard to walk back once they're live.

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

AI Adoption & Integration

Every leadership team is being asked what their AI strategy is, and most engineering orgs are experimenting without a clear line to business value. I map out where AI actually earns its keep — accelerating refactors and legacy modernization, or supporting the business directly — and help your team act on it without the hype.

Good for: teams evaluating where AI fits their stack, legacy codebases ripe for AI-assisted refactors, non-technical leaders who want a straight answer on AI

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 get the architecture right before you commit to it. The decisions made in the first weeks of a rebuild determine the next three years.

Good for: teams facing a major technical inflection point

Technical Hiring & Team Assessment

Hiring technical talent is a bet, whether it's a founder hiring their first CTO or a CTO hiring the next senior engineer or lead. I run the technical evaluation — structuring the interview process and pressure-testing whether the person you're about to trust actually has the judgment the role needs.

Good for: founders hiring their first technical leader, CTOs and leads growing their team, boards vetting a CTO candidate

CTO Mentoring

Being a CTO for the first time is lonely — every decision feels irreversible and there's rarely anyone internally who's done it before. I work 1:1 with first-time CTOs and engineering leads on the calls that matter: how to structure a team, when to push back on the roadmap, how to talk to the board.

Good for: first-time CTOs, engineers stepping into their first leadership role

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 architecture decisions that look small today and get expensive to unwind in a year.

Leaders sizing up AI

Who keep hearing they need an AI strategy and want a straight, non-hype read on where it actually helps.

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.
