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.

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 😉
