Top SchoolStuart Leitch is a Senior Principal Security Engineer and seasoned Java/Spring application developer with over two decades of commercial experience and 14 years in focused software roles. Currently on Oracle’s Ethical Hacking Team, he blends deep application security expertise with hands-on development, particularly in unit testing and secure coding practices.

A detail-oriented problem solver, he often pairs security-first thinking with product-focused design to deliver resilient, maintainable systems.
