Turn ambitious ideas into products, technology and teams that work.

Senior product, technology and AI leadership for companies building, changing or fixing something important. I have been the engineer, the founder and the executive, so I work at whatever level the problem needs.

Fractional, interim or advisory CPO, CTO, CPTO, Head of Product or Head of Engineering. I also train teams in AI, and when the problem needs building, I still build.

Worked with Treebytree · adidas · Reebok · Schiphol Group · DPG Media

You have an ambitious idea, but turning it into the right product is harder than it looked.
You need senior product or technology leadership without hiring another executive.
You know AI matters, but nobody owns what to do about it.
Product, design and engineering are all working hard, in slightly different directions.
Your transformation has produced projects and meetings, but not acceleration.
The technology under the product is becoming the constraint.

That is usually where I come in: when you need to move faster without creating a mess you’ll spend the next three years fixing.

Facing something like this?

Talk about it

What I help with

Eight ways in. One connected practice.

Product, technology and AI problems rarely arrive separately. Start with the one you recognise and we will follow it wherever it leads.

Product Leadership

Build the right thing, and build the organisation capable of doing it repeatedly.

For organisations that need senior product leadership, a clearer direction or stronger product practice. I work with leadership teams and directly with the teams building the product.

Strengthen the product organisation

AI Strategy & Adoption

Move from talking about AI to actually becoming good at using it.

What does AI mean for your products, your people and your competitive position? No AI theatre. No transformation programme built around PowerPoint. Find where AI creates real leverage and start there.

Digital Acceleration

Transformation should make the organisation faster, not heavier.

I help organisations improve how products are conceived, built and operated. Digital transformation when necessary. Digital acceleration whenever possible. The measure is simple: can the organisation

learn faster,decide fasterand build faster?

Product Development

From ambiguous idea to working product.

I help organisations move from concept to something customers can actually use, with your internal team, an external development partner, a temporary project team or specialists assembled around the problem.

I am not a software agency. I take responsibility for keeping product, technology and execution connected.

Show me the problem

Design Systems & Design Engineering

Turn fragmented interfaces into a system teams can actually build with.

Design, tokens, components, code and products work best as one connected system, not five separate artefacts. I come at it from both sides, the design system and the engineering system, and increasingly as the structured context AI tools need to build coherently.

DesignTokensComponentsCodeProductsAI agents

System & architecture: Strategy, audits and modernisation for multi-brand and multi-product systems, component libraries and fragmented legacy UI.
Tokens as architecture: Token structures that carry decisions across brands, products, platforms, themes and states: primitive, semantic and component layers where they fit, plus naming, governance, Figma variables and the DTCG format. The right architecture depends on your operating model, not a template.
Delivery & adoption: Design-to-code workflows, accessibility, documentation, governance and contribution models that teams actually use.
AI-ready systems: Machine-readable tokens, component metadata and design context that coding agents can consume, for example through MCP, so they reuse your components instead of inventing new interfaces.

Design systems are becoming more important in an AI-native workflow, not less.

When AI can generate interfaces and code in seconds, producing UI is no longer the hard part. Producing the right UI consistently is. A structured system gives people and AI the same components, constraints and vocabulary. AI amplifies the system. It does not replace the thinking behind it.

Where this comes from. At adidas and Reebok I developed a multi-brand design system adopted across adidas, Reebok, Ivy Park and collaboration labels, covering components, tokens, accessibility and governance. At PVH I introduced a design system in the innovation environment that later scaled across brands including Tommy Hilfiger, Calvin Klein and Havaianas.

Engagements range from a three-day audit and roadmap to foundation sprints, system builds and multi-team migrations. A complete enterprise design system is not a two-week job.

Talk about your design system

AI is a new layer of capability across products and organisations.

AI changes what products can do and how organisations work. Treating it as a separate project misses that. It moves the questions.

Not only~~How do we add AI?~~

What becomes possible now that wasn’t possible before?
Which workflows should fundamentally change?
What should humans remain responsible for?
What new products can now exist?
What should we deliberately not automate?

I combine product and engineering experience with an AI-native workflow, so work that usually needs several specialists and long hand-offs moves faster. Experience determines what is worth doing and whether it is right. AI helps me apply that judgement faster. I stay accountable for what gets made.

Across the whole workflow

Research
Product discovery
Strategy
Analysis
UX
Prototyping
Engineering
Testing
Documentation
Communication

Model-agnostic by design.

I work across the leading AI ecosystems, including OpenAI, Anthropic and Google, and choose tools for the problem, your requirements and your security constraints. The names will keep changing. The approach will not.

I can work inside your existing approved AI environment or use my own professional toolchain. Your confidentiality, data protection, IP and security requirements always decide which tools are used.

What the time buys

AI Opportunity Workshop

Identify and prioritise concrete AI opportunities across the business.

Product Strategy Workshop

Clarify who the product is for, what problem it should solve and what matters next.

Product Discovery Sprint

Move an ambiguous opportunity towards something testable.

Leadership Alignment

Align product, technology and business leadership around priorities and decisions.

Digital Acceleration Workshop

Identify the organisational bottlenecks preventing teams from moving faster.

Architecture & Platform Workshop

Make the important technical decisions before expensive implementation begins.

AI for Product Teams

Practical training and a working session for product, design and engineering teams.

Your own

Custom workshops designed around the problem you actually have.

Plan a workshop

How I work

Start with the problem.

Step 1

Understand

The business, customers, product, organisation, technology and constraints.

Step 2

Challenge

Question assumptions and separate the important problem from the visible symptoms.

Step 3

Decide

Turn ambiguity into clear product, organisational and technical decisions.

Step 4

Make

Turn those decisions into something tangible: a strategy, experiment, roadmap, prototype, capability or working product.

Sometimes that takes a workshop. Sometimes I stay for a year. The engagement should be no larger than the problem requires.

The interesting problems don’t respect department boundaries.

A product decision shapes the technology.

A technology decision shapes the customer experience.

AI changes both, and increasingly changes how the organisation works.

My value is moving between those layers without losing the thread: from an executive decision to a product workshop, an architecture discussion or the implementation itself.

See the whole system. Change the right part.

I started by making things.

Audio became software.

Software became products.

Products became teams and organisations.

Eventually, I found myself leading the companies building them.

That path is why I’m equally comfortable discussing a business model with a founder, a product decision with a team or an architecture choice with engineers, and why I still like making things myself.

How I got here

Audio engineering
Product management
Frontend engineering
Engineering leadership
Product & technology leadership
Founder
Executive leadership

AI now runs through all of it.

The move from engineering into product started early. At Galaxy Studios I went from audio engineer to product manager for Auro-3D.

Who I work with. Founders, CEOs and management teams. CPOs, CTOs and product and technology leaders. Innovation, transformation, HR and L&D leaders building practical AI capability. Typically the organisation is launching something new, adopting AI, modernising how it works, or needs senior product and technology leadership without another permanent executive hire.

Pricing

What happens in the time you buy.

Six typical shapes, from three days to a long partnership. They are starting points, not fixed scopes: complexity varies, and I will say so plainly. Every engagement starts at three days, and larger commitments earn lower day rates, from €1,400 for a three-day sprint to €900 from 60 committed days.

3 days

Strategic Sprint

From€4,200

Three days to find the important problem and decide what to do next.

A founder, leadership team or existing product team that needs clarity and momentum quickly.

Product and technology diagnosis
Roadmap challenge and prioritisation
Architecture review
AI opportunity assessment
Leadership alignment
A concrete next-step plan, with limited hands-on work where useful

This is the minimum standard engagement.

5 days

Acceleration Week

From€6,500

One focused week to move an existing product or team forward.

An existing product, project or team where the foundations are in place and I can start creating value immediately.

Unblock an initiative or reshape a roadmap
Accelerate discovery
Improve product and engineering alignment
Prototype an important flow
Define architecture or establish an AI workflow
A clearer, faster path forward

The promise is meaningful progress and tangible outputs, not that every organisational problem is fixed in a week.

10 days · approx. 2 weeks For new ideas

Prototype Sprint

From€12,000

From idea to something people can see, use and believe in, in two weeks.

New products, AI concepts, internal tools, digital propositions and fundraising demos that need to become tangible quickly.

Product proposition and key user journeys
Interactive prototype or functional proof of concept
AI prototype
Technical architecture
Product narrative and investor demo
Build roadmap, scope and production recommendation

A prototype is not production. It makes an idea tangible enough to test it, show it, learn from it, fund it, or decide whether to build it.

20+ days

Build / Transformation

From€22,000

Product development, organisational change and technology foundations.

For mandates where the work needs to move beyond decisions into sustained building, change or leadership.

Product development
AI implementation
Platform foundations and architecture
Product and engineering organisation
Transformation
Fractional or interim leadership

A focused product can sometimes move from zero to production in a couple of months. Larger products take longer. After discovery or prototyping, I will give you a realistic scope, timeline and investment before we continue.

40+ days · approx. 2+ months

Embedded Engagement

From€40,000

A substantial commitment, spread across the months it needs.

For sustained product builds, interim leadership and transformations that need continuity without requiring five days a week.

€900 a day applies from 60 committed days. It is the lowest standard rate I show.

All prices exclude VAT. These are typical shapes, not guarantees. Use the calculator to see the price of your commitment.

No hidden extras. €900 a day applies from 60 committed days, used within twelve months.

I reserve a reduced rate for selected organisations whose core work creates meaningful positive environmental or social impact.

If that describes your organisation, tell me about it when you get in touch. Eligible engagements receive 10% off my standard rates.

Same work. Same commitment. A little of mine towards yours.
