Rockstar🎓
Top SchoolHongyi Duan is a software engineer and quantitative researcher with 12 years of experience bridging data science, quant finance, and production engineering. Trained in finance (Nankai University) and pursuing an MS in Data Science at Duke, he has built automated attribution pipelines, alpha-factor mining frameworks, and LLM-based user profiling systems at firms including CICC and JD.com. He contributes to open-source projects across crypto (implementing SM2/SM4 in py-gmssl) and cloud-native tooling (automation and CI/CD for Drycc's Kubernetes workflows), reflecting a mix of backend, DevOps, and research skills. Proficient in Python, C++, SQL, R and advanced time-series, econometrics, and ML methods, he consistently turns noisy financial and behavioral data into actionable metrics and portfolios. Outside work he stays active in racket sports and team games, a pattern that mirrors his collaborative, iterative approach to problem solving.
