Part-Time Freelance Bug Tester Kawsher was a great find. We brought him on for software QA and he delivered consistently for over a year, thorough, reliable, and easy to work with.

He caught issues early, communicated clearly, and never needed his hand held. Exactly what you want in a contractor: someone who takes ownership and just gets it done.

Would absolutely recommend him to anyone looking for a solid QA analyst. Thanks for the great work, Kawsher, you made our team better.
