The client needed a Linux based application that monitors and tests Wi-Fi networks, and a dashboard web platform for reports. Improved the Wi-Fi network efficiency for over 30 institutions from the USA, that are successfully using the platform, by implementing a reliable and fast backend. Gathered over 50 TB of data from around 150 monitoring devices. Skills used: Java, Spring, Hibernate, RestExpress, Swagger, Maven, Git

The client needed to separate different components from a monolith to a cloud system based on approximately 25 microservices. Reduced the communication latency from 3s to 500ms and increased throughput from 300 to 2000 messages/second by changing the communication protocol to MQTT; Saved infrastructure costs by 50% by implementing a microservice architecture; Reduced microservice management effort with 75% by setting up CI/CD pipelines using Jenkins.
