Peking University
Peking University

M.S. in Software Engineering — Peking University

Graduated in the top 2% of the program with a focus on Natural Language Processing. Admitted among 600+ candidates, ranked in the top 10. Published research on automated essay scoring for nonnative Chinese speakers in ICIC Express Letters (Vol. 3, No. 5, October 2012), indexed by Ei Compendex, Scopus, and INSPEC. This degree marked the formal transition into computer science and laid the foundation for a career in software engineering and machine learning.

Major Transition

Made a deliberate pivot into computer science from an English literature background. After earning a B.A. in English, self-studied data structures, algorithms, and programming fundamentals before pursuing a master's degree in software engineering. The transition was fueled by the same systematic approach learned in martial arts: break down complex skills into manageable components, practice deliberately, and iterate relentlessly.

Nankai University
Nankai University

B.A. in English Language and Literature — Nankai University

Ranked in the top 300 out of 500,000+ examinees in one of China's most competitive provinces for the national college entrance exam. The program focused on English language and literature, with foundational coursework in semantics, pragmatics, and other core linguistics subjects — providing an early introduction to Natural Language Processing (NLP). The rigorous liberal arts training honed analytical thinking, communication, and cross-cultural understanding — skills that later proved invaluable in technical leadership and cross-team collaboration.

🚛
Truck

Short & Medium-Haul Freight

Operated short and medium-haul freight routes using a tractor-trailer (one tractor, one trailer), managing logistics coordination, route planning, and time-sensitive deliveries. This hands-on experience in real-world logistics provided a grounded understanding of supply chain dynamics, resource allocation under constraints, and the value of precise execution.

🍳
Cooking

Culinary Arts & Family Restaurant

Reached a Level 3 chef proficiency through hands-on work at the family restaurant. Developed a reward-and-penalty system that improved operational efficiency and staff accountability. This experience taught systems thinking, process optimization, and the importance of clear incentive structures — principles that later translated directly into software engineering workflows.

🥋
Iron Hand

Early Martial Arts Training

Trained in traditional Chinese martial arts from a young age. Mastered Cotton Belly — a breathing and conditioning technique advanced enough to absorb incoming punches. Developed Vajra Palm — a striking method capable of breaking walnuts and bricks. Honed Echo Location — an auditory awareness skill refined to the point of detecting anyone's movement and position by sound alone. These practices instilled a deep respect for structured learning, body mechanics, and mental focus.
