    “I hired her once before last month to do a project which she completed but the application did not work. She assured me to pay her 100$ and then when the time comes to redo it she will redo it for me but now i needed to redo it she again asked me for 150$. i agreed to pay but even now she delivered a project with LOTS of errors. I will NOT hire her again or TRUST her words. Please stay away from her and hire someone else who provides quality work.I DO NOT RECOMMENDED HER.”

    “Yong is very skilled and has the ability superior to what you may ask of her. She will deliver the quality of work you desire at a fair price. She was great to work with. If you give her clear deadlines she will meet them. With any project, I would advise you to allow an amount of time for updates/tweaks/edits. If you do so she will help deliver quality far better than you may have wanted.”
