Client testimonials
What people I have worked with say about me.

“He has a truly unique curiosity. He seeks to gain a full understanding of how systems work in order to create the best solution given the project requirements, as well as outline how it could be improved in the future. When I have a question regarding technical stack, he is always one of the first people I go to.”

Matthew Eisner

Digital Marketing Consultant

“Passionate and really smart, Gregory’s set of both IT and non IT skills make him a first choice engineer. He always puts lot of energy in effort in his work, trying to reach results beyond requirements and always want to learn more (he shows a real interest in Clojure for instance)! His ability to integrate and work in a team, complete his technical side. I would definitely recommend Gregory.

I’ve worked on projects with many developers, and Greg is certainly one of my favourites. As someone with relatively little understanding of technology, Greg helped me deepen my knowledge of complicated concepts while presenting all information necessary to make informed decisions.

He is a great guy to have in the house!”

He has a wide knowledge base, and has a knack of finding the right technical solution for difficult problems. He is also very forward-thinking, and always considers how to make his solutions scalable in the future.If you ever get the opportunity to work with Greg — I would grab it with both hands!”

“We threw Greg a complex task under unusual circumstances and he proved himself to be knowledgable, clued-in and always results focused. He is a great team-player but also a self-directed problem solver. He knows his tools and he gets started without hesitation.”
