This was a terrible experience working with Issam, he was very interested in raising invoices but when I paid him everything thinking that he will be professional enough to fix any problems later but unfortunately he turned out to be very unprofessional and greedy. He claimed that he will improve my app by completely overhauling it (which only needed some minor fixes) but he spoiled everything. When I would ask about a functionality not working, he would first claim that it was not working in the old version too but after getting evidence from me from past app, he would agree to fix that but then he never did.
In short,
He got all the money before completing the project,
He openly refused to fix issues he had created in my app
He was really arrogant and unprofessional
Be careful before hiring him or get ready to repent like me

great work, very patient, I had some delays but he has worked great so far.
