Enhanced and maintained multiple Puppet modules, delivering new features, resolving production bugs and CVEs, and improving compatibility with newer Puppet releases across the Puppet ecosystem.

Built and maintained Puppet Agent across 10+ operating systems, including Linux, Windows, macOS, AIX, Solaris, Amazon Linux, Debian, Ubuntu, Red Hat, and Fedora, resolving CVEs, OpenSSL/system-library issues, C/C++ dependencies, and platform-specific build and runtime problems.

Modernized Puppet Agent build and test infrastructure by migrating legacy VM-based workflows to Docker, delivering approximately 20% faster builds, removing dependency on VM provisioning, and making support for new operating systems faster.

Combined the Puppet Runtime and PXP Agent Vanagon builds into a single project, simplifying the build process, reducing maintenance overhead, and cutting agent build time by approximately 2–3 days.

Built and tested Puppet Agent compatibility with Puppet Enterprise, creating acceptance scenarios across different platforms and versions to identify compatibility issues early and improve release confidence.
