PROFILE
Jacek N
Worked on the stellar/stellar-core repository to enhance build and test infrastructure over a two-month period, focusing on Docker-based workflows and CI/CD reliability. Delivered Ubuntu 24.04 support by updating Docker build scripts with conditional logic for LLVM repositories and AWS CLI installation, ensuring compatibility across Ubuntu versions and enabling timely package publishing. Improved the perftests Docker image by integrating Redis CLI and automating dependency installation for parallel catchup V2 testing, which accelerated performance test cycles. Leveraged skills in DevOps, Docker, and Shell scripting to streamline build systems, reduce manual maintenance, and align the project with evolving platform and testing requirements.

Oct 1, 2025Month: 2025-10. Focused on enhancing test infrastructure for Stellar Core by delivering a feature that speeds up parallel catchup workflows and reduces setup toil in CI. Key feature delivered: Perftests Docker image enhanced to include Redis CLI, enabling Redis-based tooling for the paralle catchup V2 mission and ensuring dependencies are installed automatically when STELLAR_CORE_VERSION ends with '~perftests'. This directly accelerates testing cycles and improves reliability of performance tests.
