ABOUT ME
C, Bash, make, Git and Linux Mentor / Co-Author of an Upcoming Book
C, Bash, make, Git and Linux Mentor / Co-Author of an Upcoming Book
I'm happy to help you with C, Bash, GNU make, Git, Linux and related open-source technologies. I've enjoyed doing this stuff since the 1990s and it's got ingrained into my memory to such an extent that I seem to remember arcane stuff (like C pointers to pointers😉) even when somebody wakes me up in the middle of the night 😎
I also have a passion for helping others to grow as software engineers. I was told I ask good questions. If you ask me for advice I won't do your homework for you, but instead ask you questions that will help you come up with your own ways to improve your code or infrastructure. 🎓
I'm also a co-author of an upcoming book on Linux: Get Started on Linux by End of Tonight – Without Breaking Your Box. Check it out at: userbie.com

Aleksander helped me research debian/ubuntu packaging and automation, suggested a much simpler path forward to unblock me. Thanks!

Aleksander is very communicative. Open for challenges. Will advise you and bring the best solution on the go.

Excellent tutor and he helped me think about things more logically as I was doing the lab assignment! I will be working with him again in the future since I have plenty more assignments that would most likely require more guidance and thinking.

Aleksander has given me great advice on how to code:) During the mentoring sessions, he asked me questions that gave me a lot to think about on how to structure the code and design the model. I felt he was one step ahead of my answers. Even the harder subjects he explained very clearly. He's an excellent mentor.

I have been a member of the core team that stood up the large-scale HP Public Cloud from scratch - over a 1000 of compute nodes. My greatest achievement has been leading the development of a comprehensive CI/CD pipeline. The system includes innovative extensions to Git. I have initiated and worked on a virtual OpenStack environment for developing software and for running automated tests. I have also been deeply involved in creating the Chef recipes that stand up our software in both the test and production environments and gained a lot if insight into how to implement (and how to not implement) configuration management. Some information on the project: https://www.devopsera.com/2014/04/federative-continuous-integration.html

I tackled large-scale technical challenges in High Performance Computing. I was doing primarily Tools Development and Performance Benchmarking of a £multi-million Linux cluster operated by the University. The machine used to be the 20th fastest computer in the world at the time of its installation in 2006. It was a contract job and a secondment from ClusterVision.
