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.

Alphabet Nederland

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. As a Chapter Lead I spearheaded technical innovation within our eco-system. This included conducting Angular upgrades and enhancing the codebase for better performance. The frontend team, comprising 10 members, was responsible for overseeing and managing 20 separate Angular projects, each an individual application.

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 😉

Siliën Sprenkels

We flew all 27 Bluebirds to Cape Town for our 2026 SKO.

Without a doubt, my most memorable SKO so far.

Not just because of the location or the activities, but because it felt like a full-circle moment for me.

At the start of the year, I set my goal to become 𝐏𝐫𝐢𝐧𝐜𝐢𝐩𝐚𝐥 𝐂𝐨𝐧𝐬𝐮𝐥𝐭𝐚𝐧𝐭.

Standing there now, sharing my journey of the past three years and giving something back to the team, made it very real.

I joined Bluebird as the 10th consultant.

Seeing 10 new colleagues join us for their very first SKO this year was something special.

I originally joined because of the opportunity to build something from scratch with an ambitious group of people.

A true meritocracy.
Clear promotion paths based on results.
No politics.
No micromanagement.

Just high performers given the chance to operate like entrepreneurs, without the downside risk.

That is exactly what I found at Bluebird.
And the good news is: we’re hiring across all teams this year.

We don’t have fixed headcount targets or a mandate to grow at all costs.
We hire when someone genuinely fits and shares the same values.

If you’re looking for a place where you can make real impact, build something meaningful, earn life-changing money, and feel like you own a piece of what you’re building, feel free to reach out.

Happy to share my journey. 

Or, if you’re curious about the companies we work with, that’s just as welcome.
