I was pleased to collaborate with James Harrison on the Enterprise Network Configuration & Infrastructure Specialist project. The quality of the work provided was good, but it could have been better to meet our expectations. Unfortunately, the delivery was slightly delayed, which caused some disruption to our schedule. We do, however, appreciate his efforts.

James completed the Intrusion Detection Systems (IDS) project for us. The quality of the work was fairly good, and the system appears to be working as intended. However, we found communication to be a bit challenging at times due to his busy schedule, and it was difficult to get timely updates on the project status. We had hoped for a bit more detail in the final delivery.
