I'm a quantitative financial analyst and algorithmic trading data scientist with over 15 years of professional experience in technical and trading roles at hedge funds and major trading companies. I'm an expert at all aspects of systematic trading, going from raw idea, to fully automated systematic trading strategy. Strategy design & signal development Whether you arrive with a rough sketch or a fully-formed hypothesis, I help translate it into clear rule sets or statistical signals. Robust back-testing I build event-driven test environments that respect market microstructure: realistic fills, spreads, latency, and transaction costs. Applied machine learning (when it adds value) Some problems benefit from additional pattern-detection—regime classification, order-flow imbalance, or adaptive position sizing. Where appropriate, I incorporate ML techniques, but only when they improve risk-return relative to simpler rules. Deployment & oversight Strategies can be delivered as semi-automated tools (you review signals, click to trade) or fully automated pipelines posting orders to Interactive Brokers, Alpaca, or exchange APIs. Independent model review Funds often retain me for a “second opinion” on in-house or vendor models before capital is committed. I examine code, data-handling, leakage risk, and performance attribution, then provide a concise report highlighting strengths, weaknesses, and remedial steps. Expert witness & litigation support I assist in cases involving algorithmic trading, model risk, or market abuse—providing clear technical analysis and expert testimony. --- I'm very laid back about how engagements begin, and I appreciate that clients are keen to have conversations with multiple freelancers before choosing one. I'm happy to have a call and chat through your ideas and what I can add while you're deciding. Whilst I'm not new to quant finance, I am new to Upwork, and I've set my rate artificially low while I get some initial reviews. Pls see my work history, bio, and website for more information.
