About
Firmware architect/lead engineer for automotive LiDAR sensors, designing RTOS-based, layered firmware and solving high-throughput real-time constraints using DMA and lock-free buffering. Built ROS nodes to bridge embedded sensor output to higher-level perception (point clouds, diagnostics, configuration) while isolating real-time logic in firmware. Established an end-to-end CI/CD pipeline with GTest unit tests plus SIL/HIL automation and Dockerized build/test environments.

Key Strengths
- Firmware architecture for real-time LiDAR sensor systems (layered design: HAL/BSP, real-time core, services)
- Real-time performance optimization under high throughput (reduced ISR workload; DMA + lock-free ring buffers)
- ROS integration with embedded firmware for sensor ingestion, diagnostics, and configuration
- Pragmatic handling of ROS non-real-time constraints (kept time-critical logic in firmware; async buffering/timestamps in ROS)
- Closed-loop motor/servo optimization using runtime telemetry (voltage, encoder position/speed) and residual error tuning
- Built automated CI/CD with unit, SIL, and HIL testing and per-build diagnostic reporting using Dockerized environments
