Worked on the apache/tomcat repository, delivering backend enhancements and robust bug fixes across HTTP, WebDAV, and configuration management. Focused on aligning HTTP status codes and Range header handling with RFC standards, improving interoperability and reducing client errors. Addressed edge cases in JSP URL generation and enforced stricter range request validation, while expanding unit and integration test coverage for reliability. Enhanced WebDAV access control and HTTP 405 response compliance, and introduced plain text rewrite map support to streamline configuration. Tackled protocol-level issues such as HPack decoding overflow, demonstrating strong skills in Java, JSP, and server development with an emphasis on standards compliance.
