      Product Design Review from Sofia Diaz

      I had an idea and vision, which intent helped me bring to life. We required a platform that would be usable on different types of mobile and desktop devices, as well as work on different browsers. We went through the process of designing the product and building an MVP. Their UX designer evaluated the mockups I gave them. Then, they gave me some suggestions on how to improve the product and provided a UI designer, who built the interfaces. From there, intent handled the following stages of product development. We went through several iterations based on user feedback for the MVP, and every feature was QA-tested before release. Now, we continue to improve the product on a monthly basis.

      I have had an positive experience working with Exaud on expanding and maintaining several software products. Our software consulting technology stack is quite wide, from embedded development to mobile game dev, making it challenging to find the right partner knowledgeable in a number of these areas. The Exaud team is professional, flexible and continues to provide the development expertise we require to fulfill our project needs on time and budget.

      We have a very long history of working with Exuad, which in itself is about the best endorsement you can have. We have been working with them on projects for going on 10 years and they are our go to external dev team. Georg and team are not only very talented they are highly ethical. To me the later point is the most important, you can trust that they will provide high quality work and you can absolutely trust them on the business side.

      Web Development Review from James Leonard Ehrlich, DVM

      I wanted to outsource front end development while maintaining back end services myself. They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used. The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have. Their professionalism and competency were impressive. I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.

Sources

DesignRush sustains a directory of over 30,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
