    PHP MySQL Programmer / HTML / CSS

    United States - Tests: 4 - Portfolio: 4

    20 Years experience designing and developing complex systems using relational database methodology. Bachelors Degree in Computer Science. (GPA 3.63) I can make MySQL and PHP do anything. My favorite saying is: "If you can dream it - I can make it happen!" - I have worked for small business as well as large corporations like: Johnson & Johnson, GMAC Insurance, Florida State College, and Peco Energy. I recently completed an assignment which had been "attempted" by 5 other programmers who had failed due to the complexity of the system design... They said it couldn't be done, and I did it! All code is written concisely, and with the utmost in efficiency, style and professionalism. I have a proven S.E.O. methodology which consistently positions the clients site at the top of the search. I have experience in setting up and implementing the GATEWAY INTERFACE with AUTHORIZE.NET to accept Credit Cards using the Advanced Integration Method (AIM). I am also ranked as a "Top Rated" Developer here on UpWork, and received 5 Stars out of 5 while on Elance from all but ONE client over the last 3 years! (He gave me a 4 because, as he said: "No one is perfect"... When I asked him what I could have done to make him happier, he replied: "Nothing, everything was great!... But I don't give anyone a perfect score!" - Then, a week later, he offered me another job! Ha! And to top it off... I am one of the most reasonably priced contractors on Upwork!... I would rather have a long-term client who comes back to me over and over, than to try and make as much as I can on one job. I stay in constant contact with the client, and allow you to see what has been done "so far" so you can give me input as we build your system. Now let's quit bragging about past accomplishments and get started on Your Project!
