Our Work

Below are some examples of the web and mobile application development projects we've had the privilege of working on.

Web App / Integration


The client was in need of a solution to simplify their sales process. We created a web app that provided an integration between their accounting package and eCommerce platform.

Multiple Integrations / Responsive Website


This system was a rebuild of an existing project. The scope was to improve performance and introduce new functionality so the business could easily expand.

Mobile App / Integration / Web-App Backend


For this project the client required a rebuild of an existing Mobile App to introduce all new functionality and design, and bring it up to date with current technology.

Web App / Systems Integration


gemSync was design to provide a seamless integration between Autotask and Sage Pastel Accounting, transferring billing data automatically with no user intervention.
