Bio
Paris Apostolopoulos
I had the opportunity to work closely with Kostas for almost a year. I also had the honour to mentor him while working on the same team. Kostas is a talented engineer that has a lot of potential. One of the first things that you will notice about him is his personality. Always open to learn, always humble and eager to take advice. This is the most important thing for people with his experience, to be able to reflect on the feedback received and then use it for his next steps. His technical skills are very complete and I think its a matter of time (future years) to expand even more. He is well diversed and open in terms of technologies and he does not suffer from the syndrome of sticking to a particular technology or solution. His attitude and diversity is one of his strongest points that will help him grow rapidly as a professional in the future. I am sure going to miss working with him day to day, a very reliable developer and colleague.
