My work attitude is very flexible and I am very much willing to listen to and understand the needs of the clients to ensure that my clients get what they need and expect. I can also provide solutions that may meet the client requirement with reduced costs. I have a strong hold on communication which makes it easier for the client to interact with me on a regular basis and helps in eliminating gaps in the requirement and output. I am available on Skype, IM, mail, phone depending on the client preference. I can assure the clients that hiring me would provide a positive outcome. I will deliver the requirement in the agreed deadline. I will provide a timely and regular/daily update of the status to make the customer at ease on how the work is progressing. Once I am being given the requirements, I would take the complete ownership of the development and will consider the task as completed only after the client is satisfied with the outcome. Before delivering to the client, a complete round of testing will be done on the developed product to ensure that the product is free of defects as much as possible, This testing ownership will be my responsibility and the client need not pay any additional cost to accommodate this testing.My responsibility will also include deploying the application on the client side if the client needs it so that the client need not worry about the product running at their end. I hope I get a chance to prove what I commit.
