Technical industry? No internet? No Problem

The GEX desktop application interfaces with custom hardware to provide medical technicians with exactly what they need.


GEX Corporation is dedicated to providing the highest quality dosimetry-related products and customer service for the radiation processing industry worldwide. GEX provides the software and hardware to facilitate FDA compliance for the process of cleaning medical equipment using radiation. The team at Hatton Point was enlisted to build a measurement and reporting application that interacts with spectrophotometer radiation measurement hardware. The existing application was spreadsheet-based and in use for over 15 years with customizations specific to each customer.


Hatton Point was challenged with replacing a spreadsheet application with a modern, native application in a web disconnected, highly regulated environment. To reduce the GEX team’s support costs, the new application would need to allow for seamless updates and customer specific configurations within a single code base. This particular challenge constrained the team from using common web technologies for deployment and support. The product released to the end user would also need to meet 21 CFR Part 11 FDA data retention and auditing compliance.


The Hatton Point team selected the Microsoft WCF Windows application framework to build the next generation dosimetry control application. This scalable toolset, including the Microsoft.NET framework, allowed the team to build an application install package that can be easily deployed to an internet-less world. With each version released, the update package contains all of the information to migrate the application and database to the latest version without manual user or technical intervention. GEX Corporation’s customers are confident their data is safe and validated for future audits. The development team leverages automated unit and integration tests to ensure new features and improvements reduce the risk of bugs into the data calculations and data retention process.


GEX Corporation has reduced their support costs by deploying a single installed app to their diverse clientele around the world. The support team can provide updates to their end users with a validated upgrade package in the diverse, disconnected world of dosimetry measurement. Their end users can confidently provide on-demand auditable reports and data access to the FDA and international compliance agencies. Hatton Point built an application that will allow GEX corporation to continue their growth into the next 15 years by removing the complexities of supporting customer specific configurations and installs.
