    Excellent experience with Tzvi. Would gladly hire him again. Truly outstanding communication and cooperation. When faced with "oddities" in the database and programming that were beyond his skill set, Tzvi would take the extra time and make additional effort to find resources that allowed him to move the project constantly forward.

    PHP Developer for Backend Administration Pages
    Tzvi's work was exceptional. <br /><br />Tzvi is extremely skilled at PHP/MySQL coding, and picked up very quickly on our specific database setup, company-specific jargon, etc. His communication was timely and effective (and in flawless English). He was able to complete the project on time, with changes and additions along the way, exactly to our original specifications. He also made several helpful suggestions of his own for how to improve security, efficiency, etc. I hope to work with him again in the near future. Thanks!<br /><br /><br /><br />
