XI LLC can also handle all of your Desktop needs for Windows or Mac as well as responsive web design.

Validation and Verification

With all the development that takes place there is a need for Quality Assurance or Validation Engineers to ensure the requirements have been implemented accordingly and that the product is robust with minimal anomalies. Not only is our QA team well trained in the various platforms and Operating Systems and devices, but they are also experienced in various industries including medical, gaming, embedded, and more.
