Absolutely fantastic Job. Not only completed the programming of PLC controller to our requirements with some complicated requirements . Went above and beyond what i asked and provided a much more practical solution than i had asked for. The program is in use in a commercial product and achieving consistent sales and the program is faultless. I have no hesitation in recommending Ognyan O for your project. At times we received a response to questions at a weekend, never more than a few hours to wait
