Sepirak Fintech Infrastructure

Overview

Sepirak, a rapidly growing fintech company, needed to build a secure, scalable, and reliable infrastructure to support their financial services platform. This case study explores how we implemented a modern cloud-native infrastructure using Google Cloud Platform (GCP), Kubernetes, and ArgoCD.

Challenge

• Handle increasing transaction volumes with strict performance requirements
• Ensure regulatory compliance and security
• Implement reliable CI/CD for rapid feature deployment
• Maintain high availability across multiple regions

Solution Architecture

Google Cloud Platform Foundation

We leveraged GCP's global infrastructure with the following core components:

• Virtual Private Cloud (VPC) - Isolated network infrastructure
• Cloud IAM - Fine-grained access control
• Cloud KMS - Encryption key management
• Cloud Audit Logs - Comprehensive audit trailing

Kubernetes Infrastructure

The application runs on Google Kubernetes Engine (GKE) with:

• Kubernetes - Container orchestration
• ArgoCD - GitOps-based CI/CD
