PROFILE
Zuzana Miklankova
Over a three-month period, Zmiklank worked on the envoyproxy/envoy-openssl repository, delivering three features focused on dynamic cryptographic capability and build environment improvements. He implemented runtime SSL curve, cipher, and signature algorithm discovery using C and OpenSSL, replacing static lists to ensure up-to-date compatibility and reduce manual maintenance. His changes enhanced configuration accuracy and interoperability across environments by leveraging OpenSSL APIs for data-driven capability detection. Additionally, Zmiklank standardized the Docker-based build environment by externalizing the builder image reference and simplifying CI scripts with bash and Docker, resulting in reproducible builds and streamlined maintenance for the system programming workflow.

Sep 1, 2025In 2025-09, delivered OpenSSL/Envoy Docker Build Environment Standardization for envoyproxy/envoy-openssl. Externalized the builder image definition by reading ENVOY_BUILD_IMAGE from the GitHub Actions workflow, removed the inline Dockerfile, and simplified openssl/run_envoy_docker.sh to rely on the centralized builder image. This change improves build reproducibility, reduces pipeline drift, and simplifies maintenance, enabling faster onboarding and upgrades of the build stack.
