Career advice for data professionals

Many people have helped me in the past with work-related challenges, so I like to return the favor and help others who are struggling with their career. I work in the dynamic world of Data Science and AI, so I focus my efforts on people from that field (for instance, data engineers, machine learning engineers, data scientists, data analysts), or people wanting to get into it.

I usually advise starters, young professionals, mid-career seniors, and expats. In one short session of about one hour, I give valuable tips on networking, the use of LinkedIn, and playing to your strengths. And I ask a lot of questions. My aim is to enable you to find a suitable job by yourself, now and in the future.

If you’re interested, then reach out at, or connect via LinkedIn. I’m looking forward to it!

Did I mention that it is free? I only ask that you also help others when you get the chance.

Common questions I encounter

  • Should I work for a small company, or a large one?
  • Should I work as a consultant, or be part of an in-house team?
  • What companies are active in my area of expertise?
  • Which role should I take? Data Engineer? Machine Learning Engineer? Data Scientist? Data Analyst? etc.
  • How can I best find vacancies?
  • How can I compare job offers? (hint: it’s more difficult than just comparing gross salary)
  • I want to work as a Data Scientist, but I’m cleaning data all the time.
  • I’m a software developer, and the Data Scientists in my team don’t understand what it means to produce a mature IT product.
  • I’m a Data Scientist, but I seem to be giving presentations most of the time. What do I do?
  • I want to work with algorithms, but I’m mostly making dashboards. Is that normal?
  • I want to move from Data Analysis into Data Science. How do I proceed?
  • I want to move from Software Engineering to Data Engineering. Is that possible?
  • I’m in meetings all day. Is that normal?
  • Should I focus on technology, or move towards a business-oriented role?


Expats typically approach me with specific questions regarding the Dutch job-market in data:

  • Where do I look for vacancies in The Netherlands?
  • What is the maturity level of company X?
  • What are current trends in data and AI?
  • What networking events can I visit?


Your expertise in the field has been incredibly helpful, and I appreciate your willingness to share your knowledge with me. You’ve not only helped me gain clarity on my goals but also provided  valuable tips for job interviews, and they really made a difference. Now I enter the interviews with a better mindset and I can see the results. The talk really helped me to build my confidence again, and that led me to talk with my current boss to ask for other opportunities and now I am better in the job I currently have.


Martijn, zeer veel dank voor ons gesprek. Het heeft me veel waardevolle tips, inzicht en vooral positieve motivatie opgeleverd!


Martijn kindly agreed to help me with my career development. I wanted to know if I’m competitive on the Netherlands market, what median salary I can expect, and how to improve my current resume, LinkedIn, and CV. He provided all the answers during the call and thorough comments on my resume after it. Because of that, I became more confident on the interviews and reached stages that I hadn’t reached before. I really appreciate what he has done for me and wish him luck in his personal journey as well.


Martijn is very easy-going and patient. He provides me with lots of resources. Meanwhile, he encourages me to try, to take the initiative to get feedback and adjust myself, which makes me more confident and motivated.


Door zijn kennis en ruime werkervaring heeft Martijn mij geholpen bij het uitstippelen van een vervolgtraject. De gesprekken zijn nuttig en brengen nieuwe inzichten. Kortom: zeker aan te bevelen.
