I'm highly experienced in developing web projects using ASP .Net. I started with web forms using ADO .Net, and now mainly focus on MVC and Entity Framework. Besides web sites, I also develop web services with WCF and Web API. By using web services, I can de-couple my applications with a multi-tier scalable structure. I'm good at database design, performance tuning and data processing. I developed a data processing logic processing 1G data daily within 10 minutes' time.
