Additionally, he was the client-facing security expert assisting Intigriti's Customer Success team, explaining technical vulnerabilities to clients and giving advice on assessments day-to-day.

Gaining technical experience

As a student, Martijn never passed on an opportunity to improve his technical skills.

In an internal IT team from a factory, and in a team of seasoned cyber security experts.

These experiences helped shape Martijn into a confident technical professional.


Security internship at The Security Factory

At The Security Factory (tSF), Martijn did a spontaneous internship where he learned a lot during the introductory day of one-on-one coaching, and got to apply his existing skills with the newly gathered techniques to assist the pentest team for multiple real-world projects.

Firstly, he attacked and reported on the full networking infrastructure of a client. Afterwards, the team got to work on a web platform. Lastly, they found and reported multiple security flaws in a mobile application.


IT department at Greenyard

On the IT department of Greenyard Prepared, Martijn joined the system admin group for the summer.

Working with this very specialised company has taught him the value of optimising workflows.

Empowering others

During his time at Hasselt University, Martijn loved to empower others in any way he could.

He started as the student representative for computer science, and quickly became the go-to contact point for existing and new students.

Those early moments of empowering others motivated him to teach kids how to code and help a friend in their videography business.


Programming coach at CoderDojo

At most once a month, Martijn spent his time as a coach at CoderDojo Hasselt as a volunteer. CoderDojo organises workshops to teach children and teenagers the basics of computational thinking.

CoderDojo Hasselt offers programming in Python or Scratch, Lego Mindstorms and Minecraft (redstone and mods).


Camera assistant for Tim Vervoort

Helping to record a dance show, a theatre... Without any experience with professional camera equipment, Martijn went on to help a friend who found himself suddenly short staffed.

Martijn gained some knowledge about (handling) cameras, do-s and don't-s for lighting, recording angles... But most importantly: satisfied clients and a friend back on track.

Organising events

For dozens and hundreds of people.

As the lead organiser of TEDxUHasselt, Martijn organised multiple successful editions of this event for hundreds of live attendees.

He also led Spark Your Idea, a student entrepreneurship event, and UHCTF, a creative Cyber Security competition for computer science students at Hasselt University.


Lead organiser of TEDxUHasselt

After four years of actively organising the yearly TEDxUHasselt event, Martijn can proudly look back on many successful editions.

These events shared powerful ideas to a live audience of upwards of 700 people. Allow Martijn to highlight the edition where he was the lead organiser: TEDxUHasselt 2019, Bright Ideas.
