Mission-critical SaaS platforms that cannot tolerate lost background jobs or single-node broker outages frequently search to hire a freelance High-Availability RabbitMQ Quorum Queues, Redis Sentinel/Cluster & distributed worker programmer. I am Aldian Fazrihady, a Senior Freelance Backend & Infrastructure Programmer.
Core High-Availability Message Broker & Worker Capabilities
- RabbitMQ Quorum Queues & Publisher Confirms: Replacing fragile classic mirrored queues with Raft-consensus Quorum Queues, mandatory publisher confirms, and dead-letter exchange (DLX) retry topologies.
- Zero-Loss Worker Shutdown & Visibility Timeouts: Configuring `acks_late=True`, `reject_on_worker_lost=True`, and graceful `SIGTERM` drain hooks on Kubernetes and AWS ECS so container scale-in events never drop in-flight jobs.
- Queue Priority Isolation: Separating sub-second transactional webhooks and OTP emails from heavy 10-minute PDF/AI batch jobs so bulk imports never starve interactive users.
Frequently Asked Questions
Why did our fast email/webhook tasks stall when a customer uploaded a 50,000-row CSV?
When all tasks share a single default queue, a burst of slow batch tasks monopolizes every worker process. Routing tasks into dedicated `realtime`, `default`, and `bulk_batch` queues with separate autoscaling worker pools eliminates head-of-line blocking permanently.
