How we re-architected a monolithic financial dashboard into a highly scalable, real-time microservices ecosystem.

Project Brief

How we re-architected a monolithic financial dashboard into a highly scalable, real-time microservices ecosystem.

The Challenge

Nexus Finance was struggling with database deadlocks and slow API response times during peak trading hours, leading to user churn and negative app store reviews. They needed a complete backend overhaul without downtime.

Our Solution

We implemented a Strangler Fig pattern to gradually migrate their Node.js monolith into isolated microservices. We introduced PostgreSQL read replicas, Redis caching for active sessions, and a new React frontend optimized for fast rendering of real-time trading data.
