During a two-month period, Unlair focused on containerization and DevOps challenges across Stirling-Tools/Stirling-PDF and supabase/cli. In Stirling-PDF, Unlair updated Dockerfile configurations to support JDK 25+ on Debian, modifying JAVA_TOOL_OPTIONS and JDK_JAVA_OPTIONS to stabilize builds and prepare for future Java upgrades. For supabase/cli, Unlair addressed Docker socket binding issues for the Vector container on Linux, ensuring compatibility with Docker Desktop by aligning host path usage with Linux best practices. Working primarily with Docker, Go, and Java, Unlair delivered targeted solutions that improved build reliability and deployment readiness, demonstrating depth in troubleshooting and environment-specific configuration.
