Worked on upgrading core WebAssembly runtime dependencies for the envoyproxy/envoy repository, focusing on improving compatibility, security, and maintainability of the WebAssembly execution environment. The effort involved updating proxy_wasm_cpp_host, wasmtime, and wamr to their latest versions, ensuring smoother execution of wasm modules and reducing long-term maintenance risks. Leveraged skills in build systems using Bazel, CI/CD pipelines, and dependency management to maintain end-to-end traceability throughout the process. The work included updating dependency manifests and release notes, providing clear documentation of changes and compatibility considerations, and establishing a robust foundation for future updates within the Envoy WebAssembly ecosystem.
