"Chen has been a very stable and efficient worker during this long-term project. He's my go-to choice when I want to have a task done without explaining or fixing things afterwards! Can only recommend him!"

"Zheng performed excellent work. He communicated very well, was very good at listening to the requirements, asking good questions, and ultimately meeting the goals. I'd happily work with him again."

"Dadior is very professional and completed the task well! He also found another error and fixed it for me. He definitely knows what he's doing!"

"Dadior completed the task that had been bugging me for hours very fast. He also fixed another bug i mentioned, that was not part of the original task. Super professional and knows what he's doing in React + JavaScript."

"Dadior was excellent. He has very high level expertise. He developed a repository that automatically processed data periodically to produce combined datasets, a relatively complex process. In the end, his coding work was superb. He communicates very well and thoroughly, and is responsive with messages, and his English is fluent, and we understood each other well. He worked with me every step of the way. There were several things that I didn't have any knowledge of or understand, and he worked through it with me by chatting and through video sharing, setting up a virtual machine and connecting it to my project repository. I had a list of things to do, and he knocked each one off the list. He got the job done exactly as I needed it done. He makes sure he's doing everything right the whole way through, and the quality was excellent. This was a job that he used to establish himself on upwork, and he will be worth hiring for you, and I will be working with him again for sure."
