I migrate Jenkins pipelines to GitHub Actions — preserving all logic, eliminating plugin sprawl, and reducing CI maintenance overhead. Whether you have 3 jobs or 30, I map each Jenkins concept to its GitHub Actions equivalent and deliver clean, documented workflows.
Migration scope covers: Jenkinsfiles and scripted/declarative pipelines; shared library migration to reusable workflows; stage/parallel job mapping; agent configuration to GitHub-hosted and self-hosted runners; credentials/secrets mapping with migration guidance; and environment-specific promotion logic.
I deliver a migration summary document explaining every decision made, a side-by-side validation showing both systems producing green builds, and optional Slack/Teams notification integration as part of the new pipeline.
Share your Jenkinsfiles and job configurations to start. I can work from exported files if you'd prefer not to grant repo privs. Both Jenkins and GitHub Actions run concurrently during transition — nothing gets cut over until you're confident.
