Developed and delivered domain URL normalization for input processing in the projectdiscovery/subfinder repository, focusing on enhancing backend data consistency. The work involved implementing logic in Go to strip URL schemes and path components from input strings, ensuring that only bare hostnames are passed to downstream processes. This normalization reduced parsing errors and improved the reliability of domain analytics across pipelines. The feature was built with a comprehensive suite of unit tests, reflecting a test-driven approach and attention to input sanitization. Collaborative development practices were demonstrated through co-authored commits, contributing to stronger code quality and maintainability within the project’s backend systems.
