PROFILE
Willis Berrios
Over ten months, contributed to LLNL/Surfactant by building extensible plugin management, centralized database configuration, and robust SBOM generation workflows. Leveraged Python, JavaScript, and YAML to implement a plugin CLI, unify database management with TOML-based metadata, and introduce a symlink-aware filesystem graph for accurate SBOMs. Enhanced CI/CD reliability using GitHub Actions and improved security tooling integration with Grype. Refactored core components for maintainability, modularity, and cross-platform support, addressing data integrity and error handling. Delivered features that improved deployment consistency, data processing, and supply-chain visibility, while collaborating on code quality and documentation to support ongoing maintainability and business value.

Mar 1, 2026March 2026 (LLNL/Surfactant) focused on delivering a robust, symlink-aware SBOM (Software Bill of Materials) workflow and improved traceability for software entries in environments with symbolic links. The core deliverable was a symlink-aware SBOM filesystem graph (fs_tree) with path injection, enhancing accuracy, reproducibility, and compliance readiness of SBOM generation. The effort rested on a single feature work item, with a clear momentum toward stronger supply-chain visibility and robustness in diverse deployment contexts. The work was advanced through a co-authored commit, reinforcing collaboration and code quality across the team.

Aug 1, 2025Month: 2025-08 — LLNL/Surfactant: Focused on stabilizing security tooling in CI. Key feature delivered: Grype installation reliability improvement in the test suite by refactoring install_grype() to use the official Anchore endpoint, simplifying the installation, ensuring Grype is on PATH, and always pulling the latest release. This work reduces test flakiness and accelerates secure-scan feedback in CI. No separate major bugs fixed this month; primary impact comes from reliability and maintainability improvements in the security-testing workflow.

Jul 1, 2025July 2025 monthly summary for LLNL/Surfactant: Focused on CI reliability and SBOM quality. Delivered two core features with clear business value: 1) CI concurrency groups for GitHub Actions workflows to ensure only a single workflow run per branch/workflow, reducing race conditions and speeding up CI; 2) Graph-based relationship model with a NetworkX MultiDiGraph and updated CycloneDX/SPDX SBOM writers to generate SBOMs from the graph. These changes improve CI stability, reduce wasted compute, and enhance SBOM traceability and accuracy. Notable commits: f55c4cf4db9436b9897bf0c02065ba1eab1d6ea9, 10e89bc03a6f71caef8638bd2d51de36a01d5ba1.

May 1, 2025May 2025 monthly summary for LLNL/Surfactant: Focused on data quality and reliable vendor data handling. Delivered a targeted fix to the vendor field data structure to store vendor information as a flat list of strings, correcting a nesting issue and preventing incorrect appending of nested lists. This change strengthens data integrity for vendor-related analytics and downstream systems, and aligns with ongoing data model improvements.
