      Software Development Review from Michael S.

      We selected Azumo to develop our software. We transitioned from another development company, so Azumo was initially responsible for migrating our existing code and environments. We are currently still working with Azumo as our nearshore software development team on adding new items to our software.

      Azumo helped us migrate our existing UIs into a new framework, creating reusable components and the infrastructure needed for future development. The developer they assigned became a seamless part of our team, always punctual, responsive, and a great fit overall.

      We needed to create a project for our online pharmacy platform and found Endertech on the web. Gabe Richards and Cheyne Phillips were extremely professional, friendly, informative, and responsive to our needs and questions. Beyond their technical expertise and vast experience, this team is creative, solutions oriented, engaging and incredibly easy to work with.

      Bill Corley's Review Sourced from Google

      I engaged Endertech to make my vision of a niche marketing website a reality. The team at Endertech were creative in finding solutions to accomodate my specific functionality and look and feel desires for site throughout the development stages and delivered a product beyond my initial expectations. I was "wowed" by the end result. I will be continuing to put my trust in this organization for more of their very capable consultation and services as the site launches and ramps.
