Industry 4.0 Innovation Project

A microservices-based solution that integrated different domains of expertise into a unified software platform. The solution resulted from an applied research project for one of the largest agribusiness companies in the world (the name is under NDA). My role involved managing the project's software team and acting as a software engineer and software architect. Among the activities was integrating Java and Python-based microservices written by multiple teams within the project.

I also designed and developed an industrial sensor data collecting tool based on Apache Kafka and MongoDB capable of handling different protocols (OPC UA, REST, and MQTT) from thousands of sensors. The solution involved running advanced analytics algorithms to produce near real-time results. A React-based web application was developed as a user interface and included real-time monitoring dashboards built using WebSocket.
