Jacky

Over 10 years of experience in embedded systems, system software, and large-scale product development, delivering complex products from early engineering validation to mass production across Apple, Google, ASML, Dell, and UAV platforms.

My expertise spans embedded Linux, C/C++, Python, firmware development, system integration, automation, debugging, and cross-functional engineering execution across hardware, firmware, software, manufacturing, and global engineering teams.

Recently, I have expanded my focus toward Artificial Intelligence and AI Systems Engineering, with interests in Large Language Models (LLMs), Transformer architectures, Retrieval-Augmented Generation (RAG), AI Agents, multimodal AI, Vision-Language-Action (VLA) models, and embodied AI systems.

Leveraging my background in system-level engineering and large-scale product integration, I aim to bridge foundation models with real-world intelligent systems, embedded platforms, edge computing, and robotics applications.

My focus is on building production-ready AI systems by integrating AI models with software platforms, embedded devices, cloud services, and physical environments. I enjoy solving challenging engineering problems at the intersection of AI, systems, and real-world products.
