PROFILE
Tomasz Gromadzki
Tomasz Gromadzki engineered robust CI/CD pipelines and backend infrastructure for the daos-stack/daos repository, focusing on build determinism, security governance, and system observability. He introduced explicit OS versioning and Docker-based isolation to ensure reproducible builds, while integrating tools like Jenkins and GitHub Actions for automated testing and packaging. Leveraging C, Python, and shell scripting, Tomasz unified logging formats, automated vulnerability management, and streamlined dependency updates through Dependabot and RPM alignment. His work addressed memory safety, improved test reliability, and reduced operational noise, demonstrating depth in DevOps, system programming, and configuration management to deliver stable, maintainable release workflows.

6 Commits • 6 Features
Mar 1, 2026March 2026 (2026-03) delivered security governance improvements, CI/build stability, and platform readiness for DAOS. Documented the decision to ignore the Jackson-core vulnerability GHSA-72hv-8253-57qq due to Hadoop 3.4.2 coupling, with rationale captured in .trivyignore and trivy.yaml to preserve auditability. Upgraded CI to EL9.7 as the main build/test target to improve compatibility and clarity, and refined image_version control for explicit OS targeting. Raised minimum ABT stack size to 24k for md_on_ssd and added unit tests to verify behavior. Introduced a dedicated Docker runner to isolate resource-intensive fault injection tasks, boosting CI performance and stability. Updated build/config to Leap 15.6 to support newer Go compilers and align with vulnerability fixes. Expanded Dependabot Go scans across multiple active branches to strengthen dependency security. These changes reduce risk, accelerate developer velocity, and ensure DAOS remains buildable across current platforms and compilers.

Oct 1, 2025Month: 2025-10. Key features delivered: Jira Integration: Dependabot workflow fixes for Jira issue creation, aligning with Jira v3 API and ensuring proper description formatting. Major bugs fixed: CI Provisioning: Handle Empty NVMe Directory on Leap 15 by updating nvme_limit to verify existence/non-empty '/sys/class/nvme/' before detection, preventing provisioning errors. Overall impact and accomplishments: Automation reliability improved across Jira issue creation and CI provisioning, reducing manual intervention and flaky CI runs; Jira issues are reliably created via Dependabot workflows and CI provisioning no longer errors when no NVMe devices are attached. Technologies/skills demonstrated: Jira v3 API compatibility, Dependabot workflow integration, Linux/CI environment hardening, filesystem checks in CI scripts, and adherence to signed-off commits.
