* Developed and deployed a computer vision-based AI system for wafer defect detection on the cloud.* Engineered an AI-driven circuit design system using reinforcement learning, which generates tens of thousands of logic gate designs overnight, compressing a six-month team effort into one month.* Implemented and deployed a multimodal AI librarian with LLM and RAG to enhance internal knowledge management.* Consistently diagnosed and resolved code inefficiencies for the team, often boosting speed by over 10 times through algorithm optimization and process parallelization.* Engineered and launched a resume recommendation system utilizing causal AI.

Real-time Strategy Battle Game AI Agent* Generate AI agent in real-time based on individual player level (elo) with difficulty adjustment.* Optimize computation efficiency in production environment - apply a single generalized model to different difficulties and levels.* The AI agent defeated more than 70% human players without players noticing their opponents are not humans.* Related techniques: Q-learning, Actor-critic, A3C, IMPALA, Population-based learning, CNN, LSTM, Relational Network, Attention, Pointer network, DockerGame Level Automatic Testing System* Boost level testing efficiency - find out bugs which humans testing team cannot find with thousands of AI testers in hours.* Allow game designer to review thousands of different stage clearing way generated by AI testers to improve game design.* Related techniques: Auto-deploy, Kubernetes, Docker, CNN, LSTM, IMPALA

[Data Structure and Algorithm course] * Design a final project evaluation system back-end * Setup and maintain a C++ online judge system * Set homework questions, correct the exam papers, answer the questions from students
