Professional Summary

Hands-on architect and engineering leader with 25+ years designing, building and running production systems, from hospitality reservation and loyalty platforms to logistics ordering, financial education and credit-data platforms. Founder of Neptune Consulting, where I own architecture and delivery for client platforms on AWS, Azure and GCP and implement much of what I design. SRE Lead at Equifax for fraud, identity and compliance platforms on Google Cloud. In 2026 I have run an AI-native delivery practice: AI agents I built and direct write most of the code, held to the same tests, linters and review gates as people, while production stays deterministic. Previously Director of Integration Architecture at IHG, leading a team of 50+.
