ELEKS Reviews & Testimonials
Software Development Review from John Armstrong
ELEKS was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. They’ve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
Software Development Review from Mark Battcock
We are very happy with our ELEKS partnership; the dedication of the team is exceptional. We would certainly recommend ELEKS and would be happy to work with them again. In fact, they continue to be our partner for the 2nd phase of the CDX project to add even more customer services to the website.
Software Development Review from Huntly Christie
What impressed me about ELEKS is the culture. There is a very strong culture of discipline and performance, and software is a profession where discipline is very important. Good software development can only happen with a strong work ethic, and I think the ELEKS team really understands that.
