Senior🎓
Top SchoolAnthony Lloyd is a senior developer with 11+ years building high-performance, rightsized C# and .NET Core systems for finance, specialising in P&L, risk, VaR and portfolio optimisation engines. He combines deep quantitative training (Oxford MA, Durham MSc) with practical experience delivering order management, trading and bitemporal embedded databases across hedge funds and banks. A pragmatist who prefers simplicity, he has repeatedly pushed the performance frontier—contributing benchmark-winning C# and F# implementations, creating a 60% faster Dictionary in collaboration with Microsoft, and developing MKL.NET and advanced testing libraries (e.g. performance features for Expecto). His work favours repeatable, testable designs that reduce operational overhead and logging while enabling numeric algorithm optimisation, including native-code techniques. Now at DRW, he brings a rare mix of domain knowledge in risk models and hands-on systems engineering focused on measurable speed and robustness.
