Zain is extremely thorough and professional. He caught issues that would have been embarrassing at launch and his annotated screenshots made every bug crystal clear to fix. He went above and beyond across multiple rounds of testing, including a full regression test, and was always responsive and easy to work with. Highly recommend!
