FinTech Platform Modernization

Modernizing a legacy banking platform to support real-time transactions and stronger security.

The situation

Arc Tech was operating on a 15-year-old monolithic backend system that couldn't handle modern transaction volumes, lacked real-time capabilities, and had significant security vulnerabilities. The system experienced frequent downtime during peak hours and took weeks to deploy new features.

The approach

We implemented a comprehensive modernization strategy involving microservices architecture, cloud migration to AWS, and implementation of DevOps practices. The solution included real-time transaction processing, enhanced security protocols, and automated deployment pipelines.

What changed

Reduced transaction processing time from 3-5 seconds to under 200ms
Achieved 99.99% uptime with zero downtime deployments
Decreased feature deployment time from weeks to hours
Enhanced security with multi-factor authentication and encryption
