The project was about enhancing and modernizing a truck scale system to improve operational efficiency and data accuracy. New features — including traffic-light control, extended weighing data, and updated receipt generation — streamlined operations for end users. Extensive refactoring reduced maintenance overhead, clarified data models, and increased test coverage, enabling faster, more reliable feature delivery.
As a fullstack developer, I helped unify multiple legacy traffic control systems into a single modern platform. By breaking down a WebLogic monolith into Spring Boot microservices and integrating Active Directory SSO and messaging with ActiveMQ, I improved system stability and scalability. I also enhanced the user experience with a refreshed WPF client and supported operators through testing and training. The result was a seamless transition with zero downtime, high code quality, and full adoption across traffic centers—earning strong praise from leadership
