Viktor Sinzig, CEO & Co-Founder at Halfy Hour
I've worked with the GRT Team for about a year now. They've built a web and mobile (iOS & Android) application for our company and the experience has been fantastic. The entire team is dedicated, hard working, and has deep technical knowledge.We have been assigned a project manager who ensures everything is completed on time and on budget -- they are all an absolute pleasure to work with. I look forward to working with them in months to come. I highly recommend their work!
Ron Herman, TeamFound
For an advertising/web business, we required mobile responsive site. We hired GRT to re-structure the front-end, so it responds well to mobile and tablets. They did a great job in that effort, retaining the design, and adjusting to our requirements. Their work included a design phase where we could see how the site would look in mobile. We have a technology director in-house. So we were working quite closely with GRT's developers.

GRT team worked very smartly to complete the contract on time with high quality code. Throughout the development process, they paid meticulous attention in contract details; I am at most satisfied, and definitely I will hire them again. Without any reservation, I would gladly recommend GRT team to anyone for high quality code and on time delivery with affordable cost.
