Built dynamic, stateful multistep forms with conditional stepper logic, implemented custom role-based access control for granular access control. Deployed the application via BuildPiper for streamlined delivery.
Engineered backend services using Spring Boot, Docker, and OpenShift (OCP); implemented caching and data purging with live reload capability and added secure access through basic authentication.
