"Tuan helped us set-up a data processing center in Vietnam and have been really helpful in consulting us with data strategy. They provided us with technical advice and management resources in Vietnam. Their team is very driven and responsive. It has been a great experience working with them."

Tuan le Mau was instrumental in consulting on the workflow app for the Cloudnician project. He ramped up quickly on the construction industry’s problems; he saw how legacy software could benefit from a less is more approach; he identified data bottlenecks that would produce more efficiency once architected. Tuan also provided key feedback on the back-end development process and front-end UX/UI. Insightful, reliable, and a pleasure to work with, I highly recommend hiring Tuan as a software consultant. It was time and money well spent.
