PROFILE

Matthew Kocher

Worked extensively across Cloud Foundry repositories, delivering features and reliability improvements in bosh-agent, bosh, and stemcell builders. Focused on infrastructure automation, this developer enhanced network configuration, provisioning, and deployment logic using Go, Ruby, and YAML. In bosh-agent, they implemented kernel-aligned network interface validation and robust error handling, while in bosh and bosh-linux-stemcell-builder, they added cgroups v2 support and streamlined CI/CD pipelines for Apple Silicon and ARM64. Their work included refactoring deployment recreation logic, improving Windows bootstrapping, and optimizing containerization workflows, resulting in more stable releases, reduced test flakiness, and improved cross-platform compatibility for cloud infrastructure deployments.
