Summary
Dan Shannon is a seasoned technology leader and Head of Architecture with 30 years’ experience designing cloud and enterprise platforms and currently leading Architecture, Cloud and Common Platforms at McMillan Shakespeare. He combines strategic board-level thinking with hands-on delivery—shaping cloud-native platforms, platform engineering, integration and automation so organisations see business value from the first sprint. Dan has repeatedly built and matured architecture practices across industries (financial services, retail, telco and government), led major transformation programmes and created reusable delivery platforms such as Marlo’s MDEP running on managed Kubernetes. He is equally fluent with legacy systems and migration strategies, knowing when to modernise versus when to preserve critical legacy capabilities.
