Building data & AI to revolutionize organizations.

I'm a builder. In nineteen years I've started and sold six companies and an ecommerce agency, written a book, and led teams of marketeers and developers. What I like most is the seam where strategy meets code: setting the goal, then building the thing that hits it.

About

I catch fire inventing, coding and growing things that sell.

I work from the Netherlands. Since 2007 I've built and sold six online startups and an ecommerce agency of fifteen people — and written a book about how it is done.

Today I'm Head of Data, designing and implementing the data strategy for a big European retailer. I build the warehouse on Google Cloud — BigQuery, Dataform, Datastream, Cloud Run — and lead the team shipping the AI agents that run on top of it with Vertex AI, ADK and Gemini Enterprise.

Always up for a conversation about emerging tech, building products, or the startup you cannot stop thinking about.

Data & AI

Warehouses people trust and agents that act on them. BigQuery, Dataform, Datastream, Segment CDP, Agent Platform (Vertex AI), ADK and Gemini Enterprise.

Cloud infra

Google Cloud from the ground up: Cloud Run, pipelines, IAM, CI/CD and cost control. Built to scale without becoming somebody's weekend problem.

Development

Full-stack builds that convert. Python, PHP, JavaScript, Magento, WordPress, Laravel, React Native — and plain fast HTML when that's the honest answer.

Ecommerce & online marketing

SEO, SEA, email, CRO and server-side tracking, measured properly — so growth becomes a decision instead of a guess.

Strategy & product development

Business goals turned into a roadmap, then into working software. Strategic management background, product owner scars.

Startup advice & growth hacking

Your idea, your stack or your exit. I have run the build–grow–sell loop seven times and remember exactly where it hurts.

Work

I own the data strategy across all our brands: designing and building scalable solutions on Google Cloud — BigQuery, Cloud Run, Dataform, Datastream, Segment CDP — that centralise data, improve decision-making and enable automation.

On top of that warehouse I lead the team building our next generation of AI agents with Agent Platform (Vertex AI), ADK and Gemini Enterprise. As Marketing Technology Lead I connect data, analytics and marketing platforms to power attribution, personalisation and performance marketing.

Independent work drawing on nearly two decades of online business: ecommerce, internationalisation, online marketing, web development, startups and applied machine learning.

My own ecommerce agency: online marketing and web development for clients, plus a steady stream of our own startup ideas. As owner and CTO I led a team of fifteen and was responsible for our Magento and WordPress development practice.

Sold to Zuiver Groep in January 2021.

A party game built to get friends talking. Over five hundred questions about LGBT life, dating and the rest of it, with a free tier of seventy-five and a paid expansion pack.

A product review platform, founded on the belief that you can still reach the top of Google from a standing start. A team of enthusiasts wrote up the best products of the moment: specs, pros, cons and what to watch for before you buy.

Acquired by a new owner in 2019.

A security scanner for WordPress. It watched every installation you owned and told you the moment one went out of date, before somebody else noticed first. Built in two weeks, monetised on monthly subscriptions.

Renamed WPSec.com and acquired by Triop AB in 2017.

LensOnline is the largest contact lens brand in Belgium. As external marketing and strategy consultant I advised on ecommerce, cross-channel marketing and business strategy, and worked on the internationalisation programme that took the company across Europe.

Nespresso cups multiplied fast and stayed expensive. KoffieCupster sold the same quality for less. Sold in 2016 as part of the take-over of our Italian business partner.

My own label of solar powerbanks, sourced in China and sold across several European markets, online and in physical stores.

A joint venture with ISM eCompany selling cross-channel and mobile commerce: QR code stores, mobile webshops and apps. I ran a team of five developers and owned the product and go-to-market.

A contact lens webshop started when Magento was still rough. We built it around search from day one, reached the Dutch top five and took real market share with it.

Bought by LensOnline in 2011, after which we became their preferred supplier of ecommerce technology and online marketing.
