    “Excellent! Friendly + strong domain knowledge + easy working relationship = get project done, on time, within budget n happily. (Have worked with a few Chinese programmers in the past, while they all have strong technical knowledge, there are serious communication(English) issues, unlike Piao.)”

    “Wang gets from us a rating as an exception talent. We've worked with some developers before, but Wang can do things nobody would believe are really feasible. Wang is incredibly creative and finds a solution for everything. We have developed a program that serves as a trading platform for the stock market and at the same time contains crm modules. He has developed elements for us where other programmers with good names have long since given up and have made sure that this development is not possible, even with good arguments. But wang just said, let me show you that it is possible, and he makes it easy without a long-term lamentation. we only needed 34 version updates for this complex program. that is an incredible achievement. thanks wang and anytime again. it greets you with heartfelt thanks.

    “This was a challenging project generating a complicated PDF from database data. Many pieces of data, specific control of each page, and many conditions on data to display. Initially going to use iText but went with a library to go directly from MS Word to PDF. It took longer than expected, and there were some initial performance and deployment issues, but he worked hard to get through these issues and delivered on the original project, with good performance and good PDF file. Thank you!”
