Uhray is not just a team of professional programmers and developers - we create advanced solutions by cooperating efficiently with our clients. Every stage of the development process is a tandem between Uhray and the business - we discuss all the details and nuances of the project by email or in any other convenient way. Together we bring the boldest ideas to life, whether it’s a web/mobile app or other software solutions.
Our team of experts has been offering software development services for over 8 years. We have our offices in Kansas City (Missouri) and Boston (Massachusetts).

The list of our clients includes companies like CDLlife, LittleHoots, University of Notre Dame, ASU Alumni, NextHire, Aunalytics, and many others beyond the U.S.
Thanks to our tenacity and hard work, we've been noticed by giants like TechCrunch, The Wall Street Journal, GovTech, Good Morning America, Huffington Post, CIO Review, and ABC News.
As for our values, at Uhray, we always strive to empower entrepreneurs by launching innovative software products. That's why we approach each project carefully in a systematic way as follows:
- We always test business ideas at the initial stage to set the right goals and objectives, determining the values and functions of the future product;
- Our specialists have different jobs but all of them cooperate closely with the business to provide an intuitive and engaging user interface;
- We choose layouts that will fit all parameters of the business. This is where appearance and convenience are especially important. Thus, we work hard on the color palettes, fonts, videos, animations, and other elements;
- We always pay special attention when it comes to coding so that you receive a reliable and effective solution that will reflect the vision of your core business values;
- To make sure that our solutions are 200% ready, we always test them and make all the necessary adjustments before the release.

The most frequent question we hear from our clients is about how long the project will take to complete. Most of them take 2-3 months. The cost of development, obviously, depends on several factors, with business requirements and overall project complexity being among the main ones.
