Wassim provided me with technical advice to make the right choices for producing a business survey of over 100 questions. In his recommendations, he also considered the next phase of the project: processing and analyzing the data from this survey.
He was very responsive, efficient, and perfectly adhered to the specifications I had provided. He even identified several inconsistencies in them and pointed them out to me immediately.
I would undoubtedly call on him again for future projects.
