About me

I’m Karl, a web security enthusiast, sailor, and developer dedicated to cybersecurity and ethical hacking. I specialize in identifying and exploiting vulnerabilities in web applications while also building scalable, secure software for organizations.

Web & App Security: I work and experiment with several technologies like Node.JS, Java, Kotlin, PHP and have done so for several years through my web agency Kolifink.

Blue Teaming: I’ve mastered many major EDRs, NDRs, XDRs, SIEMs, write guides and custom detections.

Pentesting: I develop own tools for security testing and perform security assessments.

Teaching & Education: Working part time at uni as a Scala/Java teacher, and worked earlier as a Python teacher. Partook as a board member in 3 non-profits whose purpose is to teach programming and hacking.
