Summary

Senior🎓
Top SchoolDavid Byrne is a Staff Software Engineer with 11 years’ experience building cloud-native Java and Kotlin microservices, currently focused on scalable FinTech systems and platform reliability. He has a strong track record delivering compliant, production-grade services—designing SOX controls, automating error recovery, and refactoring legacy code into loosely coupled components while running on Kubernetes in GCP. At Rent the Runway he led cost-saving initiatives (including a GraalVM AOT proof-of-concept) and at Cisco scaled Webex microservices through sudden traffic spikes while earning a rare internal security certification. Based in Galway, he combines hands-on engineering with operational instincts—introducing ops automation, async job redesigns that cut failures by >90%, and pragmatic solutions that replace manual toil. Colleagues rely on him for problem solving, technical leadership, and turning compliance and cost constraints into measurable engineering wins.
