Jun 1, 2025

June 2025 performance summary focused on architectural refinements, release-readiness, and CI/stability improvements across four repositories. Delivered substantial OpenNLP modularity work, consolidated ML components under a cohesive opennlp-ml hierarchy, aligned module names with established OpenNLP model conventions, and cleaned the codebase to improve stability and reproducibility of CI pipelines. StormCrawler progressed toward a formal 3.4.0 release with version upgrades and documentation updates, plus community engagement infrastructure. Storm and related tooling in the StormCrawler ecosystem received a dependency refresh (Storm 2.8.1) and repository housekeeping to ensure consistent, reliable builds. OpenNLP-sandbox also tightened CI reliability through pinned GitHub Actions SHAs. Overall impact: reduced technical debt in ML components, smoother future feature delivery, more reliable releases, and stronger community collaboration. Demonstrated proficiency in Java modularization, Maven release processes, CI/CD improvements, and GitHub Actions workflow hygiene.
