    “Chengzhe did a great job from start to finish. He correctly assessed the scope, delivered on time and was extremely responsive. I have zero complaints and I'd work with him again in a heartbeat. This project wasn't a cookie cutter app and he delivered both an iOS and Android version. Highly recommend!”

    “Chengzhe is a very dependable freelancer, he is always available, very good in communication and owns responsibility for the project. The project( upgrading and improving a MEAN stack SPA SAAS setup) took a little longer than earlier expected. This was mainly due to complexities of the setup and multiple modules. Minus few minor issues, its been a very successful project. He has delivers the project upto our expectations and keeps meeting them. He has also been very effective in handling a live setup and promptly addressing issues. We are very much satisfied and are continuing with him for other extended milestones of the same project. Will keep sharing our positive feedbacks as and when they are completed. Good work, Chengzhe.”
