Cloud Migration for a Fintech Startup

Migrated a monolithic on-premise infrastructure to AWS with zero downtime, enabling the client to scale from 10K to 500K users.

01
the challenge

What stood in the way

The client was running a legacy monolith on bare-metal servers with manual deployments taking 4+ hours. Scaling was impossible and downtime during releases was costing $50K per incident.

02
our solution

How we solved it

We decomposed the monolith into 12 microservices running on EKS, implemented Terraform for all infrastructure, set up blue-green deployments with ArgoCD, and built a complete observability stack.
