      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.

      Our company hired them to create an app designed to help expatriates find housing. A project manager and two developers from Saigon Technology worked closely with our team for the app's development. At the start, their team and ours gathered the information needed for the project and planned out how to build the product. They then designed the app's interface and added features. In the end, we launched the app successfully, and our client was satisfied with it.

      We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

How do USA .NET development companies ensure quality results?

USA .NET development companies ensure quality results by implementing a comprehensive quality assurance (QA) strategy customized to your specific business objectives. The strategy typically includes a series of tests to verify the software’s end-to-end functionality, usability, security, interoperability, and durability. It also helps ensure that the final product aligns with your business requirements and meets industry standards. 

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
