Backend

TaskNexus is a backend system engineered with NestJS to process financial operations and deliver email notifications reliably. It uses the repository pattern for database abstraction and RabbitMQ to decouple the core transaction engine from side-effect services like notifications, so the system stays available even under load.

ACID-compliant transaction managers protect data integrity, and Redis caching cuts database pressure on high-frequency reads.

Highlights

  • ACID-compliant transaction processing
  • RabbitMQ queues decouple side effects from the core
  • Redis caching for high-frequency reads
  • Modular, microservices-ready structure
