Zain is an absolute dream to work with. As a Frontend Developer, Zain and I would often work on tasks together, and I can honestly say there is no one on our team I'd rather work with. His knowledge, passion and understanding of complex tasks is amazing. He always takes the time to explain and share his knowledge. Finally, he's a natural leader who doesn't shy from the opportunity to take on more responsibility. Any team would consider themselves lucky to have Zain on board.
