Clewis1

Chris Lewis contributed to the companieshouse/psc-data-api and related repositories by delivering robust API security, authentication, and testing improvements. He implemented API Key and OAuth2 authentication, centralizing credential validation with interceptors to ensure only authorized access to sensitive data. Using Java, Spring Boot, and Docker, Chris unified endpoint access logic, addressed vulnerabilities, and expanded test coverage to reduce regression risk and improve CI feedback. He also upgraded Node.js runtimes and dependencies in web projects, enhancing maintainability and compatibility. His work demonstrated depth in backend development, error handling, and build automation, resulting in more secure, reliable, and maintainable codebases.
