    Dmitry is an expert in his domain. Was able to take a small startup with one of the most complex and secure infrastructures to the next level, all while using emerging technologies and solutions for the massive amounts of data we were capturing.

    I worked with Dmitry for around a year in a DevOps and Cloud Infrastructure Team. He was working relentlessly week after week to migrate from an old obsolete infrastructure towards a modern containerised, completely automated infrastructure. Dmitry is extremely knowledgeable, honest, organised , dependable and fun to work with. He is a highly recommended person to work with.

    I absolutely loved working with Dmitry! He’s been working as a contractor together with my development team on a number of projects over the last 2 years. Very straightforward and to the point, plus extremely knowledgeable – I always enjoyed the efficiency with which he had been contributing to the output of the team. He’s one of those people who you can fully trust and easily delegate responsibility when it comes to Infrastructure/Cloud/DevOps. Anyone would be lucky to work with Dmitry!
