About Stefan Grefen

As the Chief Technology Officer at Olea Networks, I lead the development of a complete solution that constantly determines the health of water meters. I leverage my MSc in Physics and over 25 years of experience in technology leadership, innovation, and problem solving to deliver scalable, fault-tolerant, and high-performance solutions that fulfill real-world requirements.I have extensive expertise in the telecom and IoT domains, having worked on projects such as LTE TCP performance analysis, congestion detection and improvement, and detection of encrypted videos. I also have a strong background in network and storage device drivers, high-availability and cluster computing, and web services. I enjoy translating business needs into technology and driving the technical architecture within an international team. I have contributed to multiple patents. I am passionate about creating value for customers and stakeholders, and I have helped recover millions of dollars in lost revenue for utilities through our innovative product.
