Extended and implemented the USA Food Safety solution in 11 additional organizations. Conducted onsite user training sessions for field users and admin staff.
Rolled out initial application release to cloud and on-premise infrastructure. Assisted client organizations with installation of offline application on field user hardware.
Mentored and led a team of 8 software developers in development efforts and process improvement.
Automated builds for each check in across three supported application versions, verifying the application would build and all stored procedures would execute successfully using Azure Devops and Powershell scripts.
Implemented nightly automated releases for the last successful build through Azure Devops, eliminating the need for a lead engineer to manually update more than 20 working environments and allowing QA to rely on application version and build number to determine what work was completed.
Streamlined and simplified release process for deployment team Azure Devops and a custom tool for managing DML SQL Scripts. This eliminated human error in production deployments and saved time and frustration for product ownership in understanding what issues were released between versions.
