Summary
🤩
Rockstar🎓
Top SchoolKeir Bailey is a Rust Algorithm Engineer with five years' experience building robust backend systems for finance and banking, currently developing algorithmic trading infrastructure at Keyrock. He is the creator and primary back-end contributor of Barter, an open-source Rust framework for event-driven live trading and backtesting, where he focuses on trading logic, portfolio and position management, and refactoring core modules for performance. Prior roles at Atom bank spanned data and back-end engineering, giving him practical experience turning quantitative ideas into production systems. With a Master of Physics from the University of Leeds and a study year at Waseda University, he combines strong quantitative intuition with systems-level Rust engineering. Notably, his open-source work demonstrates an eye for evolving data models and efficient market event handling that bridges research-grade algorithms and production trading demands.
