About:
My name is Mariusz Zaborski, also known as oshogbo. I’m a Polish software developer. My main areas of interest are OS security and low-level programming. During the day I work as a team leader and a software developer at Fudo Security. I lead a team in developing solutions to monitor, record and control network traffic in an IT infrastructure – the best PAM solution in the world.

In my free time I also contribute to the open source community. I’m a FreeBSD committer since 2015. My main work in this project is focused, but not limited to, creating infrastructure around Capsicum, a process sandboxing technique based on capabilities. I’m also a successful student of the Google Summer of Code 2013 for this project. I’m a team member of vexillum group, a group of computer enthusiasts. In the past we participated in some GameDev competitions with success. In 2018, with my friends from Fudo Security, we started a Polish BSD User Group (BSD-PL), which hold meetings every month.

Besides this blog I also like to share my experience and work on conferences. I was a speaker at a number of BSD and security conferences. I also wrote articles for some international and local magazines.

I live in Warsaw, a big capital city in Europe.

Please also notice that the posts on this blog represent my private opinion, not my employer’s opinion, nor of any teams I belong to or any of the open source community I work with.
