I would like to nominate Eric Wittmann from Red Hat as a committer for MicroProfile. Eric has been heavily involved with the MicroProfile OpenAPI project since day 1, and has reviewed almost all of the PRs that I have created. He's the #2 committer on the project: https://github.com/eclipse/microprofile-open-api/graphs/contributors
He joins and participates in all of the MP OpenAPI hangouts, and provides helpful guidance on issues. This would help move the project forward, as I am currently the only committer involved with MP OpenAPI, and we're not from the same company - which gives good community balance.
