About Mateusz Kocielski

I'm a programmer, system administrator and hobbyist security researcher. Fields of my interests mostly cover programming languages theory, algorithms, operating systems and computer security. My passions and abilities gave me opportunieties to take part in many interesting projects such as writing compilers, interpreters, UNIX-like operating system or designing the plagiarism detection platforms. I've got an extensive knowledge and experience in C, Python, SQL, PHP, OCaml, shell scripting and assembler x86. I've also written much more than "Hello world" in Prolog, Haskell, assembler 6502, assembler MIPS, C#, Java, HTML. Mostly I focus on the UNIX-like platforms, such as OpenBSD, FreeBSD, NetBSD or Linux, I was working with them as an administrator, as well as a programmer. In the security field, I'm interested in UNIX systems security, programs analysis and writing code in the secure way. To sum up, if you're looking for somebody who knows every single Java module in the details, then it's not me. However, if your goal is to find somebody who is able to analyze the problems from many points of view, has got wide interests, skills and wishes to know more, then you've just found one!Specialties: Linux, OpenBSD, FreeBSD, NetBSD, BSD, system administration, security, C, PHP, Python, OCaml, shell, SQL, algorithms, kernel programming, operating systems
