Client Testimonials

  • Through his work with us, Elnatan led the Android development of some of the core products of the company, part of them from scratch and others by integrating different teams work. Elnatan demonstrated a great understanding of the application inner workings as well as the Android platform. He is excellent in self learning. Most of the tasks he carried out in YKM were absolutely new for him but still, he managed to implement all independently, reaching deadlines and with great results. He is also a creative developer who finds solutions for any problem he encounters. At last, Elnatan is a team player, pleasant to work with, responsible and always on time. He's a great team player and is a delight to work with.
