Asynchronous Event-Driven Messaging Pipeline
High-Throughput Microservice & Background Job Processing
The Challenge
Synchronous API calls for resource-heavy operations (such as transactional emails and notification triggers) cause request bottlenecks, slow client response times, and system failure risks under heavy load.
The Solution & Impact
Engineered an event-driven microservice system that offloads heavy background processing to decoupled queue workers, ensuring non-blocking API performance and maximum throughput.
RabbitMQ Event Queue Topology: Designed fault-tolerant message exchanges and queues to reliably route and buffer asynchronous background tasks.
Node.js & Redis Worker Pipeline: Built high-performance worker services using Fastify, Node.js, and Redis caching for rapid job consumption and task deduplication.
Production-Ready Operations: Fully containerized with Docker for easy orchestration, featuring automated transactional email dispatches via Nodemailer and live queue health monitoring.
Tech Stack: Fastify | Node.js | RabbitMQ | Redis | PostgreSQL | Docker | Nodemailer
