Payments platform migration
Moved a payments platform processing 1.8M transactions a day from a legacy data center to a cloud provider, with a hard regulatory deadline and a requirement of zero customer-facing downtime.
Ran it as a hybrid: fixed milestones for the regulator, two-week sprints inside. Built the cutover runbook with engineering six months early and rehearsed it four times. The real cutover took 41 minutes against a 4-hour window.
