I am old certificated .NET/C# programmer working with .NET 18 years. Last 10 years I was working in support team fixing bugs and speeding-up of WEB applications that were written by another programmers. The object is well me known: slow database requests and waiting for answer from external sites are main reasons of slow work. First issue is not a big problem - eliminating Entity Framework , switching to Stored Procedures and Views will solve it. Second one requires deep analysis of the algorithm. I am living in Lithuania (+3GMT). Human languages: Lithuanian (native), English, Russian (at mother tongue level).
