About Me

HENG WAN with two kids

Born and educated in China, I earned a professional certificate in Multimedia Information Technology after high school. Over the past 12 years, I have worked across China, Thailand, and the United States, building enterprise software, games, websites, and mobile apps. I value clear communication and close collaboration with clients—it makes projects faster and better. As an independent developer, my rates are fair and not agency-level. I love my wife and children, and I treat every client with care and responsibility. I look forward to working with you.
