Work History and Feedback

  • Aug 2012

    Extend C# Event Calendar Control
    Alexander is a highly skilled professional. The task here involved building a complex new feature into the source code of an opensource C# control. While other developers struggled over understanding what was actually needed here -- let alone implementing a viable solution -- Alexander completely understood the challenge at hand and completed it in a short period of time with a perfect solution. He kept an open line of communication with me during the development process and exhibited a high level of development skills and quality work. I highly recommend Alexander and I would surely work with him in the future.
