Visualization of Satellite Data for Real-Time Satellite Monitoring and Control

• Developed and implemented a system for displaying real-time data in a web browser, used for monitoring and controlling a satellite fleet. 
• The project involved close collaboration with stakeholders and the Product Owner, with a strong emphasis on scalability and reliability. 
• The developed software is currently in 24/7 operational use.
• Architecture:
  • Designed and developed a microservice-based architecture to integrate dependent and independent data sources (.NET Core).
• Cloud Infrastructure:
  • Containerized services and deployed a cloud-ready solution using Kubernetes in Azure.
• Data Integration:
  • Integrated various APIs, including gRPC streaming, Kafka Client, ZeroMQ, and RESTful interfaces.
• Frontend Development:
  • Built a WebAssembly-based frontend using Blazor to replace a legacy system.
  • Dynamically integrated external JavaScript plotting libraries (e.g., Lightning Chart and Golden Layout).
  • Enabled live streaming of satellite data to the web browser using WebSockets (SignalR).
• User Experience:
  • Developed functionality for saving and managing workspaces and display configurations in the backend, including version control.
• Project Management:
  • Led an international team of four developers.
  • Planned and executed sprints, continuously refined the backlog, and ensured delivery through continuous delivery practices.
