Re-platforming core banking for real-time everythingBanking & Finance

A top-5 European bank · 2025

Re-platforming core banking for real-time everything

We replaced a 20-year-old monolithic core with an event-driven, cloud-native platform — cutting run costs and tripling release velocity, with zero downtime at cutover.

Faster releases

Uptime

Challenge

A legacy core couldn't support real-time payments or scale for peak loads, and every release took months of manual regression.

Solution

We decomposed the monolith into event-driven microservices on Kubernetes, introduced CI/CD with automated testing, and migrated data with a zero-downtime, dual-run cutover.

Challenge

Generic merchandising and siloed channel data meant low conversion and weak loyalty across regions.

Solution

We built a real-time customer data platform and shipped a recommendation service with experimentation built in, rolled out market by market.

Challenge

Aging data centers, rising costs, and no path to scale for peak season were holding the business back.

Solution

We stood up a governed landing zone, automated a migration factory, and re-platformed the most critical workloads for elasticity.
