• Modification of WorldWind GIS per project requirements.
• Integration of GIS tool to the project.
• Multithreaded UDP communication system that can handle multiple UAVs simultaneously.
• UI components and software architecture that other developers later used.
• HMI screens to control different types of UAVs.

Live Video Streaming and Intelligence Sharing Platform for ANKA UAV Family

Developed an intelligence-sharing portal, which had three main parts:
• Live video streaming infrastructure for multiple UAVs.
• Authentication and authorization of live streams.
• GIS module to visualize the UAV's live location and payload coverage area.
