Worked on enhancing the palantir/witchcraft-go-server repository by implementing a runtime configuration option to control HTTP/2 support in Go-based backend servers. Focused on server configuration and backend development, the work introduced a disableHTTP2 field within the Server struct and a corresponding WithDisableHTTP2 setter, allowing operators to toggle HTTP/2 protocol support dynamically. When the disableHTTP2 option is enabled, the server clears the TLSNextProto map to effectively disable HTTP/2, improving compatibility with various clients and reducing protocol-related risks in production environments. The solution was developed entirely in Go, emphasizing maintainable server configuration and robust backend engineering practices throughout the process.
