      Software Development Review from Dominique Dujardin

      The product was developed successfully and has been undergoing pilot usage. Hexagon IT Solutions managed the engagement effectively, delegating tasks and assignments between us and the team. They met timelines and communicated efficiently through Slack. Their resources also resolved bugs quickly.Hexagon makes it easy for people trying to develop software. Ultimately, Hexagon was and has been on the same page with us from the beginning. They knew exactly what we were looking for, and what we didn't want. Other software development firms jumped at us with marketing proposals, designers, and irrelevant business consulting. Hexagon IT Solutions took the time to understand who we are and offer us their services accordingly.

      Software Development Review from Mark Griffin

      Due to past experiences, Latent AI is always cautious when hiring external engineering resources for a project. But collaborating with Admios is a breath of fresh air. The agencys account manager is nothing short of professional, attentive, and understanding of client needs. Furthermore, Admios seasoned and self-sufficient engineers fit seamlessly into the Latent AI culture. The team treats and trusts them as one of their own. (Verified via email)

      Mobile App Development Review from Matt Attaway

      Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)

      Caring Gene's Review Sourced from Google

      Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

Here are some of the QA tests that US .NET development companies employ: 

  • Unit testing: Examines the software’s individual components, including module behavior, code-level functions, and error handling 
  • User acceptance testing: Simulates real-world usage, such as user interaction and how well the app integrates with business processes and workflows 
  • Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together 
  • Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
