Mark Gwilliam is a technical lead and cloud-focused architect with 12+ years delivering large-scale digital transformation and migration programmes across public and private sectors in the UK. He combines hands-on platform engineering with strategic architecture, having led cross-functional teams to migrate on-prem and Azure workloads to AWS, build distributed API platforms, and integrate legacy systems into modern PaaS solutions. His delivery experience spans GDS-aligned government services with million-plus users, energy and utilities API programmes, and commercial cloud consolidations, often working in hybrid and outsourced team models. Known for pragmatic automation and scalable design, he excels at turning complex, high-risk estates into maintainable platforms while setting up new in-house teams for long-term support. Based in England, he currently leads technical delivery at E-bx Consulting after recent stints as Cloud Architect and Solutions Architect for clients such as EcoOnline and Ofgem. A detail that often surprises colleagues: he bridges deep .NET-era architecture experience with contemporary cloud-native patterns, making him fluent across decades of enterprise technology evolution.
