Top SchoolXuan Gong is a software engineer with seven years of experience blending production performance tuning, data warehouse and ETL design, and research-grade algorithmic thinking from a Ph.D. in Computer Science. Based in Seattle, he brings strong C++, Java, and Python skills, deep knowledge of data structures, parallel and distributed systems, and practical OO and design-pattern expertise. At ADP-Cobalt he focused on performance and automation for production systems, while earlier research work covered combinatorial and approximation algorithms. An active open-source contributor, he’s fixed core issues and improved functionality in high-profile projects like Apache Kafka and Alibaba’s widely used EasyExcel library, including UTF decoding and CSV builder fixes. Colleagues know him as an avid learner, team player, and — not obvious from his resume — a former semi‑pro Dota2 player who balances competitive focus with engineering discipline.
