Daniel Searles developed a cross-repository skipped_paths mechanism for CI scan results in the semgrep and semgrep-interfaces repositories, addressing the challenge of false positives in security findings. He designed and implemented an optional field to indicate files that could not be scanned due to errors, ensuring more accurate reporting and triage. The solution involved coordinated updates across the Python CLI, OCaml backend, and ATD-derived types, with comprehensive unit testing to validate JSON serialization and scan failure handling. By aligning data models and test automation, Daniel improved data quality and reliability for distributed scan workflows, demonstrating expertise in API design and backend development.
