Henny is reallllly good! He understood my requirements very clearly and had gone beyond the call of duty to develop this complex project requirements to follow the KISS principle I gave him. I'm very happy with the results and would hire him again. Note: Henny is 100x better than many other C# developers here, which put him in 10% top coder ranking, including myself.
