Bilal is an amazing developer to work with. I definitely recommend him and his team for any scale project. He works fast, has outstanding UI skills and overall understands architecture very well. I had no issue with modification requests or with any deliveries.

Bilal and his team went beyond my expectations. We really went through all the details in the app. They suggested a function and guided me through everything since I don't have any technical background. Working with them is a pleasure as I am a returning customer, and I want them to be behind my projects.

bilal was very good to work with, the team knew what they were doing when it came to coding and were very happy to accomodate my requests. the only thing that coul dhave been improved was understanding; sometimes features i was requesting were misunderstood or took a few iterations to reach, but overall i was happy with the delivery and process :)
