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

I have successfully designed and deployed an end-to-end automation system for an online store infrastructure, focusing on operational efficiency and scalable data pipeline management.
By engineering a seamless integration between Shopify, MongoDB, and Replit, this system automates critical user flows and synchronizes transactional data in real time. Moving away from manual operations allows the business to focus strictly on revenue-generating workflows rather than administrative overhead.
Key Frameworks & Tools:
Backend & Hosting: Replit
Database Management: MongoDB
E-Commerce Infrastructure: Shopify
Next step is monitoring performance metrics to ensure maximum uptime and data integrity as volume scales.

Good call making monitoring the next step instead of more features. I would track one business metric next to uptime, like manual hours saved per week, so the owner sees the value too.
The hardest part of designing a dispute queue wasn't the table.
It was making the next action obvious.
For Ledgery, I'm testing a layout that puts work state, next action, and evidence status side by side.
Less guessing. Clearer priorities.
