.NET C# web developer to collaborate on platform initiated in 2021
We have done a one-week test sprint with Mostafizur. I greatly appreciated Mostafizur's honesty and short-term availability. We decided not to pursue with Mostafizur, as we were looking for somebody more senior, that could work largely independently in the specific technologies we use, but I'm sure he can make a good contribution in a small- or medium-sized project.
