Taking initiative, troubleshooting, and investigating

Your team on-boarded quickly and has shown so much initiative, drawing on their expertise to spot issues and make suggestions. We’ve already begun to rely on them for troubleshooting and investigating new directions for our AWS migration work and are thrilled to have them on the team, especially as the work becomes more complex.
