I'm a penetration tester and active bug bounty hunter, known in the community as Rektile404. With over three years of experience in offensive security, I’ve helped secure a wide range of companies by identifying critical vulnerabilities in web applications and APIs.

My primary focus is manual testing where i dive deep into application logic, understanding business context, and crafting impactful reports that not only highlight the technical issue but also explain the real world risks. My work has earned consistent recognition from both public and private programs, as well as direct praise from security teams.

Here are just a few of the testimonials I’ve received:

"rektile404 has the most befitting name for a hacker, as he has rekt'd our program as soon as they joined. You can expect well-written reports and communication, and someone who goes above and beyond by understanding each feature, their business purpose, behaviour, etc... then goes on to test everything in great detail. As a result, the reports are extremely clear, with a focus on business impact. Expect greatness and you shall receive it!"

"One of the best hackers we've had on our program. Signed up and immediately started ripping us to shreds. Explains things very well, has good thought process when we have supplemental questions, gracious with every bounty award."

"This researcher produced some outstanding findings for our program. Their report was well written, they retested to verify our fixes once they were in production, and they followed up in a timely fashion."

In addition to my freelance work and bug bounty contributions, I’ve been acknowledged in the Wall of Fame by the Centre for Cybersecurity Belgium (CCB) for responsible vulnerability disclosure.
