Summary
👤
Senior🎓
Top SchoolJohn Clayton is a quantitative trader and seasoned engineering leader with 11+ years of experience applying pragmatic technology to real-world problems across finance, government, automotive, ISV and consulting sectors. He has led transformations from monolithic C++ codebases to modern web and cloud stacks, introduced Scrum at scale, and served as CTO and product owner driving strategy, UX prototyping, and cross-functional delivery. Technically fluent in Python, Django, C#, Azure, Terraform, Pulumi and GitHub Actions, he designs secure, automated cloud-native environments and has recently transitioned those skills into developing and deploying multi-market quantitative trading strategies. Equally comfortable coding in small teams or steering 300+ developer organizations, he thrives on turning ideas into sellable products and building the processes that let teams own quality and delivery. An Agile evangelist who pairs hands-on engineering with commercial instincts, he often bridges CEO/CTO conversations to execution — a pattern that consistently accelerates time-to-market.
