Bringing 2+ years of hands-on experience at a top-tier Chinese investment bank (CITIC Securities) into the world of Python, automation, and AI — so you get a developer who actually understands finance. Most freelancers can either code or understand markets. I do both, and I specialize in the gap between them: building tools that analysts, traders, and fintech founders actually need. Here's how I can help you: - Financial data pipelines — scraping, cleaning, and structuring market data from A-shares, US/HK equities, crypto, futures, and alternative sources - Strategy research & backtesting — turning trading ideas into Python code, validating them against historical data, and reporting results - AI-powered financial workflows — integrating ChatGPT/Claude into research processes, from automated earnings summaries to news sentiment analysis and report generation - Investment & equity research — fundamental analysis, financial modeling, industry deep-dives, and client-ready presentations - ESG & green finance — ESG report writing, CCER (China carbon credit) advisory, and sustainable investing research - China market bridge — as a native Mandarin speaker with US and Australian education, I help Western clients access Chinese markets and data, and help Chinese clients reach global platforms My background: → B.S. in Business Statistics, Arizona State University (USA) → M.S. in Computer Science, University of Sydney (in progress) → Client Manager at CITIC Securities, one of China's largest investment banks → Research internships in futures trading and wealth management I'm responsive across time zones (AU/CN/US), deliver clean and well-documented code, and care more about solving your actual problem than billing hours. Whether it's a one-off script or an ongoing engagement, let's talk — send me a message describing what you need, and I'll tell you honestly whether I'm the right fit.
