The selection below provides a glimpse into the various projects I’ve completed for various clients over the past few years. Will your case be included soon? I’d be happy to discuss your ideas with you.
A.P. Møller-Maersk
Maersk is one of the largest container shipping companies in the world. APM Terminals, which operates more than 70 terminals worldwide, is part of the group. As part of a program to streamline terminal operations, the Flow Execution System was developed, which consists of various software components. I was a lead developer for one of…
EDSN
EDSN is a key player in the Dutch energy market. It manages systems for the various market participants (grid operators, suppliers, etc.) operating on the energy grid, enabling smooth collaboration between them. For new software development, an internal developer platform, the ITFP (IT Foundation Platform), is used. This platform already offers several building blocks. The…
UMC Utrecht
In addition to patient care, the Dermatology Department at UMC Utrecht also conducts scientific research. This research uses data collected during consultations. This data collection is often done using paper forms, which is considered time-consuming and inefficient. Therefore, in a pilot project with stakeholders, I developed a process and created an application that allows patients…
Omnihis (2)
OmniHis is a company that develops and maintains a HIS (General Practitioner Information System). As an architect/tech lead, I was responsible for the design and implementation of a renewed HIS with a team of 7 people. This has become a scalable, serverless, cloud-native solution on the AWS platform. A message-driven asynchronous architecture was chosen, in…
Omnihis (1)
OmniHis is a company that develops and maintains a HIS (General Practitioner Information System). This system is based on many local installations (at general practitioners) of their core product Scipio, supported by a number of centrally positioned services. My assignment was to modernize these services due to an outdated software stack and to develop additional…
ExamenAdviesBuro
At ExamenAdviesBuro (EAB), I was responsible for taking a custom solution in-house, which also involved setting up the internal development team. The application had been developed externally for years, but given the desired acceleration in the development of new functionalities, EAB decided to move further development in-house. We managed to manage a system that was…
HeadFirst
In this project, I briefly focused on stabilizing, maintaining, expanding, and replacing the front-end of Select, HeadFirst’s primary business system. This system matches supply and demand between clients and contractors (mostly freelancers). Profiles, assignments, bids, contracts, and documents are the core entities. At the start, I acted as interim replacement for the last internal employee…
Dakkapelreiniging.NL
Dakkapelreiniging.NL is a company with a unique approach to dormer window cleaning. The company outgrew its Excel phase and needed a system to track all its marketing campaigns and order processing. Research revealed that there wasn’t an immediately available (affordable) package suitable for the marketing process (customer selection, mailings, etc.). Following research, Marlin (PCA Mobile)…
Reclassering (2)
In a follow-up project (part of a larger project) at RN, I served as a “coaching” team leader, giving a “colleague” the opportunity to gain experience as a team leader. My main task was developing the “final” part of IRIS, a module for planning community service projects and scheduling community service recipients. To solve this…
Reclassering (1)
In this follow-up project for the Dutch Probation Service (RN), I participated as a team leader and developer in developing a new module for IRIS. This “Diagnosis & Advice” module supports staff in diagnosing the underlying causes of clients’ behavior and developing a treatment plan. It was built using the same technology as the core…
Het VisumBuro
For Hét VisumBuro, the assignment began with stabilizing the website to enable scaling and connecting with chain partners. Over time, this became much more complex, and the website had to be completely rebuilt to offer flexible integration with third-party travel partners. Phase 1 involved resolving a memory leak to ensure immediate continuity. During Phase 2,…
