Worked on the havit/Havit.Blazor repository to enhance the security and reliability of file upload components. Focused on implementing anti-forgery token support for HxInputFile and HxInputFileDropZone, the work involved updating upload methods to include token transmission and custom headers, thereby reducing CSRF risks and supporting enterprise integration requirements. Developed new end-to-end test pages to demonstrate secure upload flows and updated documentation to guide integration and highlight security considerations. Utilized Blazor for component development, with C# and JavaScript as core languages, and emphasized thorough testing to ensure robust, secure web development practices throughout the feature’s implementation.
