Maynard Kabak, Marketing ManagerCoilcraft

TSI Delivered a "World Class" Website!
TSI Applications has been a trusted vendor for Coilcraft for over 15 years. During that time, TSI has built most of the back end of our website and closely monitor and maintain our web server. They work so closely with the Marketing and IT departments that it is as though they are on staff. We have trusted them with our data and given them the responsibility that normally would go only to in-house employees.

Rapidly Delivered Top-Notch Code!
We had a pleasure working directly with TSI Applications on multiple digital projects. They did a wonderful job of implementing hi-tech complex designs for our clients. TSI consistently exceeds expectations and is very easy to work with. In a very short time, they coded complex design ideas into functional prototypes that our clients just loved. TSI Applications' development is top notch, clean and well organized. I'm looking forward to continuing working with Michael and use his services again for the outstanding quality of his work. Thank you TSI Applications!

A Response in Seconds - Not Hours!
TSI Applications knew all the complicated aspects of my e-business I didn't. They contacted me in seconds and with a SHORT afternoon phone call, it was all handled. VERY impressive.

William Stark, PresidentArzada, LLC

Extremely Happy With the Process, the Communication, and the Price!
I found the TSI team a joy to work with. We tasked them with a "vision" software project which can spell trouble for a software consultant due to scope creep. They were extremely responsive via email (my preferred medium for this type of project ) and open to suggestions and add-on's while working with us on price. End result. I was extremely happy with the process, the communication, and the price. Good job Mike and the TSI team!
