Project NEXOSPACE: IoT Building Management System

Objective: Develop an IoT device management and orchestration platform to control building operations such as room controls, lift management, and scheduling for improved efficiency. 

Team Size: 46+ developers and engineers (both onshore and offshore team)

• Managed over 10,000 connected IoT devices, including room controls, lifts, and HVAC systems, processing data streams with minimal latency (<50ms).
• Initial challenges with high-latency data processing and unreliable device synchronisation were resolved by optimising Golang’s concurrency model and Apache Kafka’s configurations, resulting in a 30% reduction in response time.
• Streamlining complex data flows from thousands of devices using Apache Nifi initially led to bottlenecks. This was mitigated by refining flow configurations, resulting in a 25% improvement in data throughput.
• Faced with scalability challenges due to growing IoT data, optimised cloud-native storage using Scylla for structured data and Redis for high-speed caching, achieving 99.95% data availability and a 40% improvement in query performance.
• Cloud resource costs were reduced by 20% through dynamic scaling strategies, balancing performance and cost by optimising the use of Scylla and Redis storage.
