PROFILE

Mark Winter

Over a three-month period, contributed to the envoyproxy/gateway repository by designing and implementing a configurable request buffering feature to enhance gateway resilience and backend protection. Developed the RequestBuffer struct in Go, updated the Kubernetes CRD, and integrated a new Envoy HTTP buffer filter to manage client request buffering and enforce size limits. This approach addressed issues with slow clients and traffic spikes, improving latency stability and resource management. Additionally, authored comprehensive documentation in Markdown and YAML, providing configuration examples and testing steps to support developer onboarding and production adoption. Work demonstrated expertise in API development, backend systems, and Kubernetes integration.
