PROFILE

Marcin Konowalczyk

Worked on the canonical/oci-factory and canonical/craft-parts repositories, delivering features that improved CI/CD automation, security, and developer experience. Built and maintained Rust container images for Ubuntu releases, upgrading toolchains and reorganizing image definitions to support new versions while deprecating outdated ones. Enhanced CI workflows and introduced automated security checks using YAML and GitHub Actions, and implemented configuration management for onboarding services like Memcached. Addressed security scanner false positives by refining Trivyignore handling, and improved Git-based workflows by reducing clone warnings. Used Python, Rust, and Bash to ensure reproducible builds, clearer documentation, and streamlined onboarding for contributors and downstream users.

Month: 2025-10 — Focused on platform readiness and developer UX improvements across two repositories. Key features delivered include: 1) New Rust Rock Image Version 1.84 for Ubuntu 25.04 in canonical/oci-factory, with configuration files for contacts, documentation, and image uploads; also includes a build toolchain bump to a newer Rust revision in oci/rust/image.yaml. Commits: e821e1f3d49277324b4f57eccd572761053238d7; 87f07afb4abe86f47641bf278a81a9b040cb4e4c. 2) UX improvement in canonical/craft-parts to suppress the detached HEAD warning during git clone by adding -c advice.detachedHead=false and updating documentation; Commit: 4cddc2ecf95f53d16e9cde1d6fd0cedd46e24307. No major bugs fixed in scope this month. Overall impact: improved platform readiness for Ubuntu 25.04, reduced clone-generated noise, and enhanced developer experience. Technologies/skills demonstrated: Rust toolchain management, image build pipelines, YAML configuration, Git CLI UX improvements, and documentation practices.

Month: 2025-09 — Delivered a targeted security-scanning fix in canonical/oci-factory to eliminate a false positive related to CVE-2025-58767 in the Ruby OCI image. The change adds a .trivyignore entry, aligning with upstream guidance and preventing scanner noise that previously caused CI delays and manual triage. The implementation was tracked under commit 7e3e29e2daee200a3a5fc18fd572d85427b7e952.
