Scaled a payments platform to 5M transactions/day
Event-driven architecture on Kubernetes with full observability, hardened for compliance and burst traffic.
Lumina was scaling fast and their payments core couldn't keep up — spiky traffic caused timeouts, cloud costs were ballooning, and compliance audits were painful. One outage could mean lost licences.
- 01
Re-designed the core as an event-driven system on Kubernetes with autoscaling.
- 02
Introduced full observability — tracing, metrics and alerting — across every service.
- 03
Hardened the platform for PCI-style compliance with audit trails baked in.
- 04
Right-sized infrastructure and added spot capacity to cut cost without risk.
The platform now clears 5M transactions a day at 99.99% uptime while cloud spend fell 45%. Audits went from weeks of scramble to a few clicks.
They made our payments platform boring — in the best way. It just works, at any scale, and costs less.
