Work Experience
11.2023 - 02.2025
Senior software engineer
Red Hat Czech s.r.o.
I worked in Kernel CI team, which runs automated tests for the Linux kernel and maintains the database, where results and known issues are stored: https://cki-project.org/ .
At this position, I have been ensuring the Kernel CI tests run cost-efficiently and quick enough both on the bare metal servers, as well as on AWS virtual machines, taking care of infrastructure part.
I have also contributed features to the CKI triager project, responsible for assigning registered bug numbers based on logs, to determine whether it is a new, or already known bug. I implemented sourcing the data from the JSON file, instead of a database.
Implemented significant cost savings in AWS while using S3, EC2, and also partially transitioned the kernel compilation and packaging workloads to the available bare metal servers, upgrading hardware where required. I have implemented cloud bursting build strategy, resulting in public cloud usage only when was needed.
Apart from the technical part of the job, I have contributed to the documentation. With quick thinking, and fast typing, high IQ and rich vocabulary, written communication and documentation is one of my strong sides.
07.2022 - 11.2023
Senior software engineer
Red Hat Czech s.r.o.
Asa release engineer, I created the process to release self-managed RHEL and OpenShift with minimal additional overhead, reusing the existing images. I have invented an original JavaScript-based solution to fill the pricing tables for all types of instances, before the API was available, making it possible to make RHEL available. I have also designed the listing, so that there is no need to re-sign a contract when the new major version becomes available at AWS.
I have considered the Red Hat security standard and proposed improvements to increase compliance, without introducing additional complexity, before moving to Kernel CI team.
Before the major project, I have been a technical lead for releases in EXD SP RHEL Compose team. I trained the new team members and was a point of contact when team members needed help.
I also participated in enterprise security standard assessments and bringing our team’s applications into the compliance with the company’s policy. As not everything was under my control, this required cooperation of other teams to implement the needed fixes on the platforms themselves.
