Key outcomes

Zero downtime cutover across retail estate
Parallel-run, traffic-shaped migration retired the legacy core without interrupting payments, statements or customer channels.
Release cadence from quarterly to weekly
Trunk-based development, automated quality gates and progressive delivery unlocked a sustained weekly release rhythm.
Operational resilience evidence ready for PRA review
Mapped important business services, tested impact tolerances and documented third-party concentration — assured by internal audit.
Cost-to-serve down 31% per active account
Right-sized workloads, FinOps discipline and the retirement of incumbent middleware contracts compounded over the first year.
