I take platform, API and CMS projects from business case to a live release, and stay on until people actually use what was built. 18+ years across marketplaces, payments and SaaS; right now I run the platform roadmap of Booking.com’s Partner Hub.
Content platforms that serve many markets at once: roadmap, migrations, multilingual rollouts and keeping legally required content correct and findable.
Integrations where two companies’ systems and contracts have to line up: specification, partner onboarding, pricing and the commercial terms behind them.
Transaction products for buyers and sellers: payment and shipping propositions, vendor selection and the operating processes a launch needs.
LLM features taken from pilot to production with measured outcomes, plus the chatbot and workflow automation around them.
The person who builds the business case also negotiates the contract, specifies the API and checks the rollout dashboard. Fewer hand-overs, and less lost between them.
What the project has to change, for whom, and how we will know it worked. Agreed before anything is built.
Requirements written with engineering and integrations specified in detail, so edge cases surface early.
Shortlist, negotiation and contract, so the commercial side is ready when the technical side is.
Engineering, UX, legal and marketing working to one plan, with stakeholders kept aligned along the way.
A pilot first where it makes sense, then the rollout, with the operating processes ready on day one.
KPI dashboards and OKRs tied back to the business case, and iteration on what the numbers show.
Some teams need a technical project manager: someone who runs an integration or migration to a date, keeps engineering, vendors and stakeholders in step, and reports honestly on progress. Others need a product owner who owns the roadmap and the backlog and decides what gets built next.
I have done both, often within the same assignment. At Marktplaats I was project manager on payment and shipping launches and managed the API partner programme; at Booking.com I own the Partner Hub roadmap and deliver the projects on it. The same role also goes by IT project manager, integration project manager or digital project manager. What matters is the work behind the title.
Tools & methods
“Quintin has a great talent for translating complex organisational issues into feasible projects, clear goals and a credible business case.”
From Q4 2026, for 4–5 days a week. A short call is the quickest way to check a start date.
Both. As technical project manager I get projects live on a date; as product owner I own roadmaps and backlogs. Many assignments need some of each, so tell me which matters most for yours.
Projects where business, partners and technology meet: platform and CMS work, API integrations and partner programmes, payments and shipping on marketplaces, and AI features that have to work in production, not just in a demo.
Online marketplaces (Marktplaats, 2dehands.be), travel (Booking.com), payments, marketing-automation SaaS (Yournii) and online media. Before that, account management in ICT.
I’m based in Amsterdam, and most of my work has been for platforms headquartered here, with launches in the Netherlands and Belgium. Booking.com’s Partner Hub serves partners worldwide in 30 languages.
Hands-on enough to specify an API, read integration documentation and talk to engineers in their terms. I still build things myself: 25+ websites and digital products through FlowFive, plus AI automations and scripts. I’m not the engineer on your team, though; my job is making sure the engineering lands.
Send the problem in one paragraph. If I’m the right person you’ll know within one call; if I’m not, I’ll tell you who is.
