Smart Factory Monitoring for a Serbian Production Plant

A chart-based monitoring dashboard (ApexCharts, Plotly) for AOI process yield at an overseas production plant, built from Figma design through the React frontend, with an existing Spring Boot API adapted to feed it — process visibility that helped cut the AOI defect rate by roughly 20%.
