Comfortable in .NET and Java, the Kotlin Multiplatform stack, and AI integrations with both proprietary and open-weights models. Master’s in Software Engineering from the University of Amsterdam.

what colleagues say

On working with him.

i.
Paul brought exceptional innovation drive to our team during his time as Lead AI and Emerging Technologies Architect. His enthusiasm for AI innovation and pleasant collaborative style made him a pleasure to work with. Paul is both as a person and as a professional a great addition to innovative teams.
Sander van de Merwe
Business Area Director, Visma
ii.
Paul was kind enough to offer his time before work hours to help me grasp programming fundamentals. He explained complex topics in simple terms, in a patient and relaxed manner. I believe beyond doubt that Paul will be invaluable to any team he goes to.
Marcel Alim
Product Manager, Baker Hughes
iii.
Paul has a really solid grasp of programming fundamentals. He wasn’t just writing code that worked; he was thinking about maintainability, testing, and how other developers would interact with his work. I’d without reservation recommend Paul for senior development roles.
Andy Lambie
Data Engineer, MostWare.Next
iv.
Paul naturally stepped into a leadership role. What stood out most was his ability to lead through influence, not authority — people followed him because they trusted his vision. He was incredibly friendly, approachable, and brought a great sense of humor.
Catrina Davis
IT Project Management, Baker Hughes
v.
Paul built a working prototype within time and budget despite a very challenging context. He is extremely skilled at explaining complex technical tasks to non-technical people. He genuinely cares about solving the user’s problem — this is the main reason I recommend him.
Clare Spencer
AI Product Manager
vi.
Paul is an exceptionally skilled software engineer, with a deep passion for designing high quality reliable software. I will be forever grateful for the knowledge I gained attending Paul’s coding dojos. His willingness to organise them during his free time is admirable.
Mihai Todor
Research Software Engineer
vii.
Paul was often the first and only point of call required for support issues. His interest in newer, more productive technologies was always evident, and a migration of his skills to Windows and Web based products was a key step in his continued professional development.

Agile Developer & Scrum Master
