Work History and Feedback

  • Oct 2012 - Dec 2012

    Senior Javascript Developer
    Very intelligent and easy to work with. Almost always very easy to get in touch with. Had one issue where he didn't reply for a week due to holiday and busy with other project. Once the communication issue was resolved things were great. He was very up front about being busy with another project which is rare for a contractor to be so honest. Two thumbs up!
