"Justin from Data Analytics Group worked on a piece of data for me which needed to be analyzed in different ways. He did exactly what I needed him to do in the time limit I needed. The communication with this particular client was excellent or should I say superb. He has clearly proved to me his expertise which I believe any person with any mathematical problems should clearly take advantage of.
This work produced would later be used as part of a presentation.
I am well pleased and would love to work with him again.
