Worked on modernizing CI/CD pipelines for the Percona-Lab/jenkins-pipelines repository, focusing on improving build hygiene and deployment consistency. Updated Jenkins pipeline scripts written in Groovy to use the current 'make build' target, replacing deprecated commands and ensuring uniform build steps across various cloud environments. Leveraged DevOps practices and Docker to streamline the build process, consolidating Makefile targets and removing obsolete entries to reduce confusion and maintenance overhead. These changes standardized build targets, making onboarding of new environments faster and lowering ongoing support requirements. The work emphasized maintainability and reliability, with all improvements delivered through a single feature update.
