Ihor was a great asset in his time with the team. Ihor was able to onboard quickly and interpret requirements to implementation just as smoothly. Ihor's hard skill with software engineering and development/coding were at or above expectations. Ihor collaborated and communicated well asking follow up questions and seeking clarification on his tasks so he could drive them to completion autonomously with little oversight and management. Will miss having him on the team.
