PROFILE
Matteo Mazza
Worked on the ktorio/ktor and ktorio/ktor-documentation repositories to improve HTTP client reliability and caching behavior. Addressed a bug in plugin installation order, ensuring HttpRequestRetry and HttpTimeout interact correctly by updating both documentation and core Kotlin code. Enhanced user guidance with clear installation instructions and aligned documentation with actual code behavior. Later, resolved a cache miss issue in HttpCache by standardizing Vary header separator handling for content negotiation, using RFC-compliant logic and comprehensive tests. Demonstrated strong backend development, API design, and testing skills, with a focus on reducing backend load and improving negotiated response performance in Kotlin environments.
