    Enjoyed working with Milen on the original architecture behind CertifID services. Very passionate about software engineering best practices. We worked closely on security related capabilities including web application security and production infrastructure access & hardening pieces. He single handedly built a lot of backend services in Azure/.Net environments. Highly recommend Milen!

    I had the pleasure of working with Milen at CertifID, where he was a Senior Software Engineer. While working with Milen, he demonstrated expertise in application architecture, system thinking, algorithm design, coding best practices, and a general mastery of programming for business applications. He was also an enthusiastic collaborator who regularly coached his colleagues through their projects and assignments. Milen was always ready to take on new challenges, learn new things, and teach his peers. He approached new problems and difficult situations with an open mind and a solution-oriented approach. I believe that any team would benefit from Milen’s skills and contributions.
