Video plus project
- Developed a real-time traffic surveillance platform to monitor live camera feeds at road intersections.
- Implemented HLS for scalable video streaming and WebRTC for low-latency real-time feeds.
- Enabled snapshot capture from live video streams for incident analysis and reporting.
- I built the frontend using Blazor WebAssembly, with jQuery for interactive UI components.
- Utilized Redis for caching and real-time data handling to optimize streaming performance.
- Managed video metadata, snapshots, and system data using SQL Server.
- Optimized the application to support multiple concurrent camera feeds with stable performance.
- Worked on an Intersection State Ingestor service to capture and store emergency vehicle movement data across traffic intersections.
- Tracked which emergency vehicle crossed which intersection, along with associated state, and timing information.
- Designed backend logic to ingest real-time intersection and vehicle events.
- Persisted ingested data into SQL Server for historical analysis and reporting.
- Ensured data accuracy, reliability, and consistency for traffic and emergency-response use cases.
- Supported traffic signal preemption analysis and emergency vehicle performance monitoring.
- Optimized data ingestion workflows for high-frequency, real-time event processing.
- Worked on migrating the existing GLANCE API from an older .NET Core version to a newer, modern .NET architecture.
- Refactored legacy components to improve performance, maintainability, and scalability.
- Replaced MSMQ-based messaging with Redis in selected endpoints to enable faster data access and real-time processing.
- Optimized API endpoints to handle vehicle preemption and speed profile data efficiently.
- Ensured backward compatibility and data integrity during the migration process.
- Improved system responsiveness and reduced dependency on legacy messaging infrastructure.
- Supported real-time vehicle tracking and traffic signal preemption use cases.
- Developed a Redis Viewer application to browse and inspect Redis keys and view their corresponding cached data.
- Implemented functionality to list keys, view values, and analyze stored information across Redis instances.
- Built backend services using .NET / ASP.NET Core to interact securely with Redis.
- Designed a clean and responsive UI for easy cache monitoring and debugging.
- Enabled developers and support teams to debug cache-related issues efficiently.
- Improved system observability by providing visibility into Redis data usage.
- Supported multiple Redis data types, and ensured safe read-only access where required.
- Developed a video server middleware service to continuously monitor live video streams in the Video Plus streaming platform.
- Integrated with MediaMTX server to manage active video streams.
- Implemented logic to automatically terminate (kick) non-continuous streams from the MediaMTX server.
- Identified and removed streams that:
Exceeded configured data usage limits
Were not being viewed by any active users
Were not configured as 24/7 streams - Designed the service to temporarily remove inactive or invalid streams, improving server efficiency.
- Reduced unnecessary bandwidth consumption and optimized media server resource utilization.
- Ensured high availability and stability through continuous stream health monitoring.
