PROFILE
Matt Leon
Matt Leon developed two core features across the envoyproxy/envoy-openssl and docker/envoy repositories, focusing on security and extensibility. He upgraded the V8 engine in envoy-openssl, applying targeted patches to proxy_wasm_cpp_host to address security vulnerabilities and improve WASM runtime compatibility, using C++ and Starlark for build system and dependency management. In docker/envoy, he engineered a flexible composite filter for response path mutation, enabling dynamic response body changes based on headers and content types, with support for complex filters like ext_proc. His work included integration testing and documentation updates, demonstrating depth in C++ development, configuration management, and Envoy filter engineering.
