Summary
Andrew Mccall is an engineering leader with ~17 years' hands-on experience and two decades of full-stack, data infrastructure and platform engineering across large-scale financial and startup environments. At Lloyds Banking Group he has twice served as interim Executive Director, driving a major federated, cloud-native data transformation on Google Cloud and leading functions from 50-900 people with full budget accountability. He specialises in moving teams from request-driven delivery to product-led, self-serve platforms—introducing golden paths, inner-source contribution models, and single-step onboarding that let teams own end-to-end data products. Technically grounded, he deliberately keeps a production-grade home lab to validate patterns before promoting them at enterprise scale, a practice that tightens the bridge between architecture and operability. Known for delivering large migrations (3,000+ batch jobs to GCP with zero incidents) and for originating data-driven roadmaps, he combines executive accountability with regular coding and platform design.
