Bio
Pawel Korycinski
Grzegorz is a highly experienced network expert who has been a valuable member of our team. He has an exceptional depth of knowledge in various vendor platforms and protocols, which has been instrumental in the successful implementation of complex network projects. As one of my direct reports, I have had the pleasure of witnessing Grzegorz's impressive ability to think outside the box and come up with creative solutions to network challenges. He is an outstanding collaborator and is always open to new ideas and approaches, making him an asset to any team. Above all, I have been struck by his dedication and commitment to delivering quality work. He has a strong work ethic and is always willing to go the extra mile to ensure that our projects are delivered on time and to the highest standards.

Grzegorz is a very hard working and inventive network and security architect. As a Cisco expert Grzegorz has been able to take those skills across a range of other vendor hardware to build and support some very complex network and firewall cloud connection scenarios for our large government clients. Grzegorz has consistently been able to lead our clients towards solutions where he can see gaps in their designs. We’ve had great feedback from the customers about how he’s managed to help fix persistent issues they have been having and his ability to create designs and solutions with very little information is a much-needed skill. Grzegorz has a very strong work ethic, going beyond what’s required to ensure the clients implementations are a success, and combined with his ability to come up with solutions for any problem he is presented with, he is a valuable asset in any organisation.
