    PHP | MySQL | AJAX | javascript | AngularJS

    India

    Website Developer for past 7 years mainly being PHP developer, also worked on JavaScript, CSS. People for whom I have worked in the past and my co-devs feel I m a master, so i would like to believe i m. For Elance Providers, I don't bid on projects until i m 100% sure of delivering it with acceptable efficiency and quality (one odd reason i have very less jobs in my kitty - also i won't win all bids). I don't have anything to show in my portfolio as i m a developer mostly writing scripts (php, python, html, javascript...) and not a designer, putting my providers designs here in portfolio would be misleading (also in some cases NDA). I believe in keeping learning new things in life and will keep doing so.
