LizardFS developer profile

LizardFS server

Hi, my name is Przemysław (pronounced pshemyswav), Przemek for short. I come from Poland.


I was born in Lublin. I could give you details like it’s the ninth largest city in Poland etc, but it’s just another ordinary city in Poland. Nothing particularly interesting about it to be honest.


After high school in Lublin I moved to Warsaw (the capital city of Poland) to study IT at Warsaw University of Technology, where I’m doing my bachelor’s. During studies I worked as an intern at Samsung where I was part of a team developing and maintaining a C/C++ library for IoT devices to communicate with cloud services. There I also created a simple but versatile cloud-service-mocking framework that helps in testing of this library.


I speak English and Polish. I know C, C++, Java, Python, Kotlin (Android). I have most experience programming in C++ and I use it on a daily basis – especially nowadays as I work as part of LizardFS team.


LizardFS: It’s open-source, it’s interesting, intimidating at first, but very exciting to work on. It makes use of low-level APIs, clever optimizations, exotic high-performance data structures and various open-source third-party libraries. There is always something new to discover in its source code. On the other hand, that’s also why it is so difficult and time-consuming to become familiar with. But it surely is a rewarding process. There are many things I have learned from its code already.


Right now we focus mainly on fixing bugs, most of which have been detected by the project’s community (thanks for that). While doing it, we try to put some effort into increasing the code quality of the parts concerning the bugs, where necessary. After that, an idea I have is to parallelize the master implementation, which currently is the main bottleneck of LizardFS, to speed up filesystem operations performed on Lizard.


I envisage LizardFS in the not-too-distant future as being a well-known solution that people trust, are satisfied with and willingly use in their environments. I would love it to become one of the top players in the field of storage solutions, one that is identified with high availability and being open-source.

We have had some interest from the community to take part in this series of articles, they will come shortly.

Introduction to the community

My name is Patryk, I was born and raised in Warsaw, Poland, not Indiana.

Warsaw is a fantastic city to live in and has a large amount of very talented programmers.

I speak Polish and English fluently, dabbled a bit in German, Spanish and Italian for a few years. Now, I could probably manage ordering in a restaurant (maybe). I concentrate more on other types of languages, C++, C, Python, Perl, Bash and a few others.

I did my masters of science in engineering and computer science at Warsaw University of Technology, along with my Bachelors degree in engineering and computer science. Most of the creators of LizardFS come from there.

During my studies I gained experience working for 2 Polish companies, Comarch and Gemius, mainly doing C++ stuff. After studies I moved to Intel as a Linux kernel developer working on the Intel puma project (google it if you like, it’s quite interesting stuff). Since March this year I have been working on the LizardFS project.

LizardFS is by far the most interesting and exciting project I have been involved with. Really! It’s a great Polish project (yes I am patriotic), started in Poland by talented MIM UW postgraduates. Unfortunately all of those brilliant minds left the project pursuing new challenges. Now I and our new team try our best to learn the code base, fix bugs left in 3.13-rc1 and develop new features. As most of you understand, learning someone else’s code is never an easy task, but we are coping. We have the benefit of some sessions with the original developers to help us get acquainted with the code faster and push the project back to its former glory.

Currently, as you have seen from the last press release we are working on fixing 3.13-rc2, we succeeded in getting the first parts of that done on schedule, now we are pushing to finish it and have a bullet proof new 3.13 version by the end of the year. LizardFS was always known for its stability, we want that back. After that we will work on improving performance by adding the Agama project mount and Kubernetes support (seems to be the most frequently requested direction for us to take). Besides that I would like to add a security layer to the LizardFS protocol, so that it can be used even in untrusted subnets.

In the future, I would like LizardFS to be an open-source standard for storing files on corporate servers and small businesses, but also on nerds’ homemade server racks. 😉

We have already had several of the community step forward and show interest in taking part in these articles, would be great to have many more.

Remember the idea is to try and pull the community together and make the project stronger, hopefully growing along the way.
