IEC 61850 Real-Time Systems: Engineered core algorithms in a hard real-time, high-frequency environment; identified a fatal thread leak (3,200 threads/sec in a 20ms cycle), benchmarked Linux vs Windows (1.1s vs 2.0s at 1,600 tasks/s) to make the case for platform migration, and led a full redesign featuring thread pooling, Control/Data Plane separation, a zero-copy Event Bus, and centralised storage.

Distributed IoT Networking: Developed large-scale IoT lighting systems facilitating real-time data interaction across hundreds of devices, achieving 40% overall energy savings. Dynamic Configuration Architecture: Co-architected a 'Cloud Template + Local Logic Engine' framework to decouple business logic from firmware, enabling dynamic hot-updates and eliminating firmware bloat Cross-Platform Migration: Led the full-stack migration from Broadcom to Silicon Labs chipsets, navigating unstable SDKs and

Streaming Protocols: Developed and optimized RTSP, HLS, and MSS protocols for live AV broadcasts, implementing low-level data synchronization across TCP/UDP/HTTP. System Refactoring: Led a large-scale refactoring of the media subsystem into a layered architecture, significantly improving cross-platform maintainability and code scalability.

---- Developed embedded software for Set-Top Box platforms with focus on reliability and performance
