    I have had a 7 years of experience in Web development, having worked for a webdesigncastle across my tenure. Over the course, I have learnt a lot and am still adding to my experiences. I think one of my distinguishing strength is the diversity of experiences I possess.I have almost 7 years of full time work experience at different types of projects. All these elements have given me a very broad point of view. My experiences also have taught me that my success strongly depends on my accountability level. Therefore, in any activity, I seek to assume responsibility for the deliverance of high quality outcomes in any times, and take ownership of all responsibilities within my own role. By joining a team, I challenge others to excel my sense of community, creative thinking and persistence in finding answers to the questions from my seniors and expect in future this will be in continue process. Moreover, I encourage my team-mates to explore the problem from different angles in order to come to mutual acceptable compromises and a practical solution to the dispute with a focus on maintaining a functioning work environment. this is the way I trust I can help to maintain a high working standard for a team. Our department successfully could increase its portfolio more than 200% and it was not possible without a high quality team activity. I am also too patient. May at the first glance it seems a strength but not about me. I usually try to be patient about bad behaviour or mistakes of others instead of talking about it and finally I get angry and reflect in a bad way. Finally I know to have a successful life both in personal and career, I need to know myself. And I am working not only to strengthen my strength but also improve my weaknesses.
