Illustrative example

Scaling a FinTech payment platform

A fast-growing FinTech payments provider

Handling rapid growth without slowing down

50,000+
transactions per second
Industry
FinTech / payments
Scale
50,000+ transactions per second
Compliance
PCI-DSS Level 1
Platform
Google Cloud

The challenge

  • Transaction volume grew 10x
  • During peak hours, processing delays hit more than 10 seconds
  • Failed transactions and customer complaints
  • Upcoming PCI-DSS audits flagged security risks

What it had to do

  • Process tens of thousands of transactions per second
  • Maintain sub-second latency
  • Scale globally
  • Meet financial compliance standards

What we built

CloudMagic rebuilt the system as a cloud-native microservices architecture on Google Cloud. Each service scales on its own, traffic is balanced across regions, and the old central database gave way to a globally consistent one built for financial workloads.
