Summary
👤
Senior🎓
Top SchoolMateusz Kocielski is an IT security consultant and systems programmer with 14+ years of hands-on experience across UNIX-like platforms, low-level kernel work, and applied security research. He combines deep C and systems expertise with fluency in Python, OCaml, PHP and assembler to build compilers, interpreters, fuzzers and kernel-space tools, and has contributed to NetBSD and FreeBSD projects. As the author of the Minerva PHP fuzzer and multiple CVE discoveries, he blends practical vulnerability hunting and automated analysis with secure coding and code review skills. Mateusz repeatedly bridges research and production—running hobby projects, speaking at security conferences, and advising on mobile, web and network security engagements. Based in Katowice, Poland, he’s as comfortable auditing trust boundaries and crypto as he is architecting plagiarism-detection and embedded systems solutions.
