    “We feel really lucky for having met Roman. Since we first got in touch we knew he was the ideal person. Responsiveness, professionalism, understanding capability, added value and ability to solve any problem, whatever the complexity, are attributes that define him. Not only our expectations were met but he also outperformed in several ways: - He corrected our mathematical mistakes - He proposed several improvements for the project Thanks to all his characteristics, we had a fluent conversation, we didn't spend much time (resources) on explaining our necessities and all our expectations were more than met. We will hire Roman for the next projects for sure! We doubt there can be anyone better than him on Freelancer!”
