    Vepa Durdiyev

    Senior C# Developer, Algorithm Development Professional

    Turkey - Tests: 5 - Portfolio: 4

    I am a senior C# developer with excellent knowledge of algorithm development and good sense of design. When designing an application my priority is not just functionality, but also performance, user friendly UI and appealing graphics. Before finishing a project I always make sure to run all possible tests so you won’t be encountering any errors in future. I have extensive knowledge of developing enterprise solutions, such as POS/CRM/ERP systems and other business management applications. In addition I also have a lot of experience creating other various windows desktop applications, such as data filtering, price comparing, profit calculating, keyword/product matching, user monitoring applications and many other. I am also a very quick learner and able to adapt fast. Here is the list of programming languages and technologies I excel at: C#, C, C++, Microsoft SQL Server, Windows Forms. My Goal is not to complete the task, but complete it in best possible way. I have a perfect rating of 5.0 and I intend to keep it so. I have never said 'no' to a bug fix, nor I ever charged for it, and I won't in future. By hiring me you don't just hire a programmer who is a professional in his job, but you are also guaranteeing yourself a life time support and bug fixing for your project.
