Full Stack Asp.Net developer
Yaseer delivered good work on this development project and I enjoyed working with him. His communication was top-notch, he met all deadlines, and his skills were reasonably strong. At one point I asked for an additional milestone and he was very forthcoming that the additional work was outside his area of expertise. I enjoyed working with Yaseer and will likely have additional jobs for him in the future.
