    “I initially dealt with Khawaja nearly a year ago. Initially he said that project would be completed in approximately 1 month. A year later and after paying him $300 and me purchasing 2 development board (including additonal components - as per his instructions). A year later, he has not shown me anything at all to show that he was working on it. At the same time, I seen him (through his feedback), working on other projects through this entire time. Unbeleivable! Be warned!”

    “Working with Khawaja was easy and smooth. He delivered on the project as promised. He was easy to work with, accommodating and met all my requirements. I will continue to work with him and will be working on future projects with him. As i had some trust issues due to the previous few freelancers, I explained that to Khawaja and he was accommodating and worked hard to earn my trust. I highly recommend Khawaja as he is very easy to work with.”
