I led the delivery of PayPal and buy now, pay later into the JohnLewis.com checkout, while we moved the whole checkout onto new infrastructure.
We needed to rebuild the checkout without customers noticing.
Customers were asking for PayPal and buy now, pay later, but the old platform made new payment methods hard to add. With millions of people using the checkout, any downtime meant lost sales.
I worked with the payment partners, risk and engineering teams to get PayPal and buy now, pay later live.
I managed the DevOps team moving the checkout onto GCP microservices.
We kept the checkout running with no downtime through Black Friday.
