...in our office you've become the stuff of legend. When we talk about something we need, we go over ways to implement it, and then someone will say 'Just let Murray do it, he'll know what to do.'

Roy Shiro, Pine Telephone

The work was delivered exactly to our specifications, on time and to budget, at a very realistic price. Murray was a pleasure to work with, fitting in to our schedule and responding to our questions promptly and authoritatively. I would recommend him to anyone needing to get things done quickly and professionally with a minimum of fuss.

Tim F, Codestream Ltd.

Over the years, what has impressed is Murray's versatility to either get involved in an ongoing project as if he was working on it from the beginning or to transform ideas into finished product while having a direct impact in the overall design of the product. Murray has [...] always delivered according to the agreed upon schedule. I highly recommend Murray for any IT consulting needs.

Murray has been very professional and efficient when solving our MySQL database issues. Murray used his MySQL knowledge and experience to successfully optimize our database. The results have been that the end users have stopped complaining about the time that their reports take to generate and are now querying more data than before.

Ted J, Ostara Nutrient Recovery Systems

Murray has been able to take our ideas and transform them into ready-to-use web applications, quickly and efficiently. Often-times we would present an idea and he would challenge us to look at the impact of our request then logically come up with a more cost effective, better solution.

John Hoy, Effectuality Inc.

Murray's attention to detail and prompt assistance helped our company immensely. Murray's no nonsense approach and constant, clear communication also reflect Kinky Logic's philosophy, which is very important. We are proud to have Murray as our technical partner!

Justin H, Kinky Logic Inc. Design

Very impressed. Murray went above and beyond what was necessary to resolve our issue. He was even willing to work out of hours in order to fit in with our timezone difference. He is obviously experienced with running MySQL on a Windows Server. We will certainly use him again for any future optimisation requirements.

It's great to see the new installation up and running. Many thanks for all your work. It took us much, much longer to get the first installation going, and even then it didn't work, and has never worked, properly.
