IT Infrastructure CI/CD support

Looking for a regular resource for IT infrastructure support. Currently maintaining github->CodeBuild->Docker->Jenkins->EC2 (with a bit of Rancher) stack. Would like to migrate to a more coherent process in Q1 2023. Right now we have a problem with the delivery and need somebody to help solve a problem. Started with a Jenkins SSL expiration. Once that's fixed we need to make sure that the ci/cd process is working smoothly.
We'd like this to turn into a long-term maintenance consulting relationship.
