  It was a pleasure to work with him; he explained everything in detail and understood my idea without needing a lengthy explanation. 5/5.

  Hammad was polite, professional and supportive throughout the whole process. He is clearly very knowledgeable about the language and framework and was very helpful in explaining concepts and answering all my questions in an easy-to-understand manner.

  I really enjoyed working with Hammad. We worked together every morning for about an an hour and a half over several days. I was able to ask questions and he could answer and explain everything. When I came up with new ideas, he found ways to implement them. Overall, he's a super polite and competent guy. I would absolutely recommend him. This definitely won't be the last time I work with Hammad :)
