@blairyang
I build Python-driven risk models, data pipelines, and systematic trading research.
What I'm looking for
I've built risk models and automated data pipelines at HSBC, improving Expected Credit Loss forecast reliability by 30% and cutting processing time from two days to half a day.
At Hang Seng Bank, I improved the digital customer journey for Cross-Border Wealth Management Connect, reducing in-branch visits by 30%. I also coordinated business, technology, and compliance teams to deliver KYC/AML-compliant system changes.
My work combines Python, SQL, financial modeling, and data engineering—from automating KYC checks at CICC to developing inventory prediction and logistics optimization models.
Through my Financial Technology master's capstone and independent alpha research, I've developed factor research and backtesting capabilities, including performance attribution, robustness testing, Sharpe ratio, and maximum drawdown analysis.
