We focus on various IT areas, from software development, cloud & infrastructure, data science & engineering, product roles and more.

Managing Partner IT

ASML

At ASML, a leader in the semiconductor industry, I contributed to developing a platform designed to provide insights into machine operations. This platform played a crucial role in monitoring for errors, facilitating timely fixes, and employing artificial intelligence to anticipate potential failures.

Due to the proprietary and sensitive nature of the technology and processes at ASML, much of the detailed information about my role and the project specifics is classified. This experience has honed my skills in handling confidential data and working within strict operational security guidelines, reinforcing the importance of discretion and integrity in high-stakes environments.

At Alphabet Lease (part of BMW Group), a leasing company, my role involved developing modular components for a complex system and leading several frontend projects.

I also contributed to the refactoring of a key application, transitioning it to a monorepo structure with Nx to improve maintainability and scalability.

Lead Fullstack Engineer

Ministerie van Volksgezondheid, Welzijn en Sport

Increasing mobility of citizens between EU countries results in a growing number of people seeking healthcare outside their own region or country. To facilitate the exchange of patient data among countries, the European Union collaborates with member states on an international infrastructure known as eHealth Digital Services & Infrastructure (eHDSI). The Netherlands is integrating into this system of national contact points with its own national contact point called the National Contact Point for eHealth (NCPeH). Through the NCPeH, healthcare professionals can digitally retrieve patient summaries from patients in EU countries requiring unplanned care in the Netherlands.

Working while being a student

During my studies, to gain practical experience, I wanted to work. I faced the challenge that no company was willing to hire me part-time. Driven by resilience and determination, I didn't let this stop me. Instead, I chose to start my own freelancing 'company' as a way to gain that experience. I've worked on a variety of projects, ranging from small websites for local artists to large-scale applications like a planning system for a major transportation company. This experience has given me a versatile skill set, making me broadly deployable in various IT roles.

The tech stack I've used includes: WordPress, PHP, Laravel, JavaScript, AngularJS, Angular, React, HTML/CSS, and React Native.

As a former developer, I redefine the kind of developer you think you’re looking for and see beyond the resume to ensure you hire the real deal.

If you're a developer or hiring manager, feel free to send me a message on work related things.

If you're a human being you can always send me a message with anything random because I like engaging with you nonetheless 😉

Advisor / investor

EXIT NOVEMBER 2024 - Together with my co-founder I started Bluebird from scratch and built it into a global agency, specialised in recruiting sales / marketing / CS and IT professionals for SaaS companies.

Bluebird is the only recruitment agency in the world without recruiters. Everyone on our team had a career in SaaS sales or IT prior to joining our team. 

What does that mean for our clients?  
-  Better qualified candidates ''it takes one to know one''
-  More and better candidates to chose from
-  Time saved, no poor interviews
-  Greatly enhanced candidate experience, right from the start

FastSpring

As Enterprise Account Executive I was responsible for closing the larger deals. Self-prospected 70% of my pipe, which resulted in a #1 position on the EMEA leaderboard and #2 globally in less than a year.

Enterprise Account Executive

Wish

At Wish I was the 1st hire for the Benelux region and one of the first employees to start up the European office. I was eventually responsible for Business Development in the Benelux & Scandinavian countries:

- Obtaining new business: sales & acquisition 
- ERP-partner contact and (API) integration
- Marketing activities
- Analysing & growing existing business (Account Management)
- Working closely with stakeholders at the San Francisco office to unlock my markets

Junior sales advisor

After a career in SaaS sales, I founded Bluebird, built it into a highly profitable global business, and exited after five incredible years. From my dad’s living room to partnering with hundreds of global SaaS companies, we supported organizations across the spectrum - from pre-seed startups to public giants - helping them scale smarter and faster.

Over the years, I’ve worked with countless founders, leadership teams and investors across the startup ecosystem. I’ve helped pre-seed startups secure their first sales hires, advised Series A/B/C scale-ups on building world-class revenue teams and supported public giants in hiring top executives. I know what works (and what doesn’t) when it comes to recruiting and scaling high-performing teams.

Now, I invest in startups and founders reshaping their industries. 

Here’s what I bring:

- Strategic Insight: Hands-on experience scaling a business from scratch to millions.
- Network Access: Strong connections across SaaS, startups, and the VC/PE world.
- Tactical Know-How: Proven expertise in hiring and scaling sales organisations.

I keep things real: my tone is direct, my focus is impact and I bring humor to the table. Business should never be boring.

If you’re building something bold or just want to exchange ideas and maybe a laugh, let’s connect.

(I’m spending more time at the beach than on LinkedIn these days)

Cheers!
