MBition GmbH.

Worked as part of Build Enablement, and SwF Runners teams, who worked on the build and test tooling, docs, platform, infrastructure, GitLab runners, pipelines, and security optimizations. These toolings and pipelines were used by various development teams across the globe to ship the software to 3 generations of Mercedes-Benz cars.
Below, are some of the tasks I did:

• Improved the execution time of the build step from 60+ minutes to be ~6 minutes.
• Improved the generation of Logical Blocks step time from 90+ minutes to be ~60 minutes.
• Improvements on pipelines' stability (10% less failures due to pipeline issues).
• Identified problems with pipeline architecture, and created the project specification for fixing them.
• Supported other teams on refactoring, and architecting pipelines for better stability/performance.
• Rewrote parts of the pipeline in golang/Docker to improve performance, stability, and releases LTS on both Jenkins and Gitlab CI.
• Implemented the Change Control Board (CCB) for reviewing tickets and improve refinement process.
