    I am well experienced in .net desktop application development and equally like to develop web application. My last experiences are based on desktop application development and Database analysis application. I have served in couple of organizations earlier and had great experience in desktop development and client relationship building. Client satisfaction is key to success in my thoughts and what I have proved during my project online. Being honest and straightforward with my client is the only reason why I am getting repetitive work from clients and repetitive good feed-backs. :)
