Project description:
"I’m looking for an expert [login to view URL] developer with proven experience implementing BullMQ in real-world projects. You should have hands-on knowledge of designing and managing queues, workers, and job lifecycles at scale.

Let me share a scenario for better understanding:

Imagine a WhatsApp marketing platform where users can onboard seamlessly by scanning a QR code and then upload an Excel file containing their leads (e.g., names, phone numbers, and related details).

Once their data is uploaded, users can launch campaigns—essentially bulk messaging operations through WhatsApp. Each user has the flexibility to create and manage multiple campaigns simultaneously. For every campaign, they have full operational control with options to start, pause, resume, and stop according to their requirements.

From a technical perspective, each campaign is modeled as a queue, and the bulk messages within that campaign are treated as jobs within the queue. This structure ensures that when a user starts a campaign, the system initiates the queue instantly, and the user retains direct control over the execution of those jobs.

This design also allows multiple users to run campaigns concurrently without conflict. Each user’s campaign operates in isolation, with independent time limits and execution cycles. Resource management and CPU intensity have already been addressed, so scalability and stability are not concerns.

I've done everything as required now what exactly I need is a [login to view URL] developer who can implement BullMQ to manage user campaigns as queues, where each campaign’s messages are jobs that can be started, paused, resumed, or stopped independently." (client-provided description)
