A fast track professional having more than 6 years of experience in developing  web applications for enterprises covering performance optimisation, progressive enhancement, usability, and accessibility. As a creative person like to be involved in jobs that emphasize innovative thinking and originality, which require in depth expertise and specialisation rather than just implementing or executing ideas of other people. As a team man with good interpersonal skills, I am willing to try new things and comfortable taking some risk whenever opportunities emerge.
