Jay has leveraged hardware, software, and wireless technology to streamline the operations, maintenance, and monitoring of data that is collected at landfills. Landfills and landfill gas in particular, along with other industries must comply with government regulations. Collecting, storing and analyzing compliance data is expensive because traditionally it was time consuming and sometimes dangerous to collect. SCS Technology developed a secure and user-friendly web-based application to identify, collect, track, and report in real-time the data required to meet compliance regulations. The components work wirelessly and are built to last even under extreme weather conditions.
Mr. Hatho also oversees the modernization and standardization of SCS’s IT organization to support the company’s growth. He is responsible for deploying modern technologies to help improve communication throughout the company and for leading the development of software products both internally and for clients.
