Piotr Berlinski is a Principal Security Engineer at Milestone Systems. Colleagues describe him as "Piotr was employee no 2/3 to join the team. Besides really good penetration testing skills Piotr has had a bit of organizational knack, when he spearheaded establishment of pentesting vendor panel from scratch, creating the RFP, criteria and managing the evaluation with the aim to choose worlds best vendors. Besides vendors this required ability to cooperation with Legal and Vendor management. Result went through audit's/reviews without a single shade of questions of being an iconic piece of work. Piotr is a great part of any team." and "I had the pleasure of having Piotr work for me at First Data. Piotr is a very talented engineer. He was able to learn new technologies very quickly and was able to perform very complex troubleshooting when required. In addition to his technical skills, Piotr is able to visualize the bigger picture for the company and translate that into direction for the team and the day-to-day tasks. One of Piotr's best attributes is his ability to communicate with both management and fellow engineers. I highly recommend Piotr as a top notch Security Engineer and hope to work with him again in the future. Kevin Hamilton Director, Cyber Security and Fraud First Data "
