• Rebuilt a KPI report from a ~2-hour query to a few seconds with a Redis caching layer.
• Integrated a production machine with Python over OPC UA and MQTT — reading and writing PLC control tags coordinated with the machine vendor’s mechatronics engineer — and built the web interface operators used inside that station’s work cycle.
• Built Power BI and Tableau dashboards for supervisors.
