Denis Courtney
Oliver worked for me for 18 months as OSS Test Engineer on nbn's Integrated Release Program from Release 16 through to 20. During this time Oliver was a valuable member of the team, often leading testing. His extensive telecommunications experience, attitude and work ethic were great strengths and he regularly took the initiative to come up with innovative improvements, developing scripts and tools and sharing knowledge around the team. Oliver would make a great addition to any Telecomms or IT team and I would certainly hire him again given the opportunity.

His good background of telecom industry and quick understanding to complicated issues enable us to achieve success in multiple projects for various customers from EMEA and NAR market. Moreover Oliver's passion and excellent communication skill make him to be a good team player in the past, and I believe, anytime in the future.
