    “Mungun is a rockstar Android programmer - truly a gem in the ocean of freelancers in Freelancer. He did some amazing work for me without being in physical possession of a very specific Android device that was a mandatory requirement for the project. This was not easy without the device but Mungun made it happen with true perseverance and programming expertise. All his code works perfectly on my Android device, exactly as I wanted it to work. I will hire Mungun again without question. You rock!!!”

    “I have been a user of this site for 15 years, going back to the rentacoder days, but this has been the worst experience I have had here. On our 2nd project, he repeatedly asked for milestone payments, with stories of needing money to to buy a sibling's birthday present. Then we got 2 months behind schedule and he would not neither deliver the code in whatever state he last left it (his excuse is his brother accidentally deleted all the files LOL), nor would he refund any $ he kept asking for.”
