June 2025: Implemented automated security scanning for the ToF repository by introducing a CodeQL workflow. The CodeQL Security Scanning Workflow (codeql.yml) runs on pushes and pull requests to main and rel-6* branches, and on a weekly schedule, enabling multi-language security analysis across C/C++, Python, JavaScript/TypeScript, and more. This establishes a security automation baseline, supports faster vulnerability detection and remediation, and reduces manual review effort. No major bugs were documented as fixed for this repository in June 2025. Overall impact includes improved security posture, standardized analysis across languages, and better readiness for security/compliance requirements. Technologies/skills demonstrated include GitHub Actions, CodeQL, YAML-based CI/CD pipelines, cross-language security tooling, and DevOps automation.
