Develop multi-robot communication middleware on ROS2.

Improved the “Smart Connect” feature, a scalable Wi-Fi setup automation process for IoT devices based on SSDP protocol, in which I restructured the code, added unit tests, and reduced the memory footprint and connection speed. Collaborated with fall detection radar imaging & home appliance companies, and integrated their products with our Wi-Fi and IoT technologies. Migrated the project build system from Make to CMake + Ninja, resulting in a 30%-70% build time reduction. Wrote Dockerfile to set up the build environment. Improved Git & code review workflows, documentation guidelines, and the onboarding wiki for the team.

Achieved Guinness World Records for The Fastest 50m Swim by a Robotic Fish, with a record of 26.79 seconds.

Lead a team of 20+ members, trained 6 juniors, and managed over HK$300,000 annual budget. Built pattern recognition for vehicle LED light source to automate and accelerate enemy targeting, with OpenCV and hue-based filtering techniques. Worked with open-source robotics projects based on FreeRTOS released by DJI Technology Co., Ltd. Implemented and tuned speed & position cascading PID control algorithm for gimbal and chassis BLDC motors, which were controlled over CAN protocol.
