Engineering Case Study // SaaS Platforms
Global FinTech Dashboard
Replacing a massively fragmented banking portal with a unified, real-time React application resolving 10,000+ daily ledger updates with zero-latency.
Provable Impact
300%Increase in Transaction Speed
The Systemic Breakdown
The legacy system relied on batch SQL jobs that frequently locked the database during volatile trading windows, causing unacceptable user-client timeout errors.
System View
The Algorithmic Resolution
We decoupled the monolithic architecture into microservices. We deployed Redis caching to handle read-heavy dashboard queries instantaneously, while writing transactional data asynchronously into PostgreSQL via Kafka message brokers.
