Think like a hacker, act like a professional
Security is not an afterthought for me. It's how I look at every system. I am best at finding weaknesses in websites, and preventing them in what I build myself.
Track record
Municipal hackathon
Participated in a hackathon organized by a Dutch municipality. There, hackers, with permission and within clear boundaries, search for weaknesses in real systems.
Deloitte CTF
Participant in Deloitte's Capture The Flag competition, which focuses on security challenges in web, network, and reverse engineering.
Responsible disclosure
Together with others, I found a vulnerability in a system used by multiple municipalities, and we reported it properly. This prevented anyone from exploiting it. Report first, never disclose without permission. My name is in the Hall of Fame of the Information Security Service.
Bug bounties
In my free time, I search for bugs within bug bounty programs, especially in web applications, where companies invite hackers to test their systems within clear rules.
Always within the rules
Hacking only works if it stays clean. That's why I stick to three rules. First, permission: I only test systems for which I have permission, or a public bug bounty program. Report, don't abuse: if I find something, it goes immediately and confidentially to the owner, with an explanation and a tip on how to fix it. Keep quiet: I never disclose details about a vulnerability without the organization's permission.
I carry that mindset into all my work. Anyone who connects an AI agent to their phone, calendar, and customer data must be able to trust that this connection will not become a backdoor. That's why, with every design, I first consider what an attacker could do with it, and only then do I build.

Educated, not just self-taught
Ethical Hacking, HBO Bootcamp
HBO bootcamp with a focus on the technical side of security: hands-on experience with reverse engineering and pentesting. Also introduced to themes such as compliance and risk management.
Practice as a learning school
CTFs, bug bounties, and hack events keep knowledge sharp. The security landscape changes every month, so standing still is not an option.
What does this mean for you?
I check your website or workplace for vulnerabilities, and I build your AI integrations securely right away. Practical, in plain language, without thick reports.
