In order to provide an extra layer of security and to comply with the standards and methods that the environment was under, Lior had to face a very challenging task involving the "darkest corners" of iOS. He did everything we asked for and hit the budget exactly. Very fun to work with and more importantly, a true professional.

Lior got a mission from us, to build a wizard and to build it from scratch.
As our API layer is not so simple to work with, together with complicated workflow to implement, we needed a great performer and talented executer.
Lior, delivered a very high quality product.
He was responsive and worked very hard to meet the due dates as some of the requirements were changed during the development time.
The final result was impressive.
Lior met all our expectations.
Lior will defiantly work with us in the future.
