“I worked with Volodymyr on same project. He is very skilled developer. He sorts most complicated tasks when nobody even dares to touch them :D He is focused on outcomes of each realized task, he has magnificent soft skills to coordinate the work between teammates. Volodymyr does not let any new bugs introduced during code reviews - he does not do them 'automatic' way but focuses on every commited line of code. I always felt that can rely on him and his knowledge on every aspect of project.”

Technical Reviewer of "Getting Started with Phalcon" Book

See projectI was one of the core contributors to Phalcon, and Packt Publishing offered me to review 'Getting Started with Phalcon' by Stephan A. Miller. This was very interesting experience (I always wanted to write a book but never had enough time) that I enjoyed very much.
Feedback from Ankita Goenka, Project Coordinator: "It was indeed a pleasure working with you. Thanks for your co-operation throughout this project. Hopefully, I get a chance to work with you again in future."
