#098: Implement Redis-Based Queue for Payroll

Category: [BACKEND]
Difficulty: ● HARD
Tags: redis, bullmq, queue, asynchronous, payroll, scalability

Description

Refactor the payroll execution logic to use a Redis-based job queue (e.g., BullMQ). This ensures that large payroll runs are processed asynchronously in the background, preventing API timeouts and allowing for better load management and job retries.

Acceptance Criteria

• Set up BullMQ worker for the payroll-processing queue.
• Move blockchain transaction logic into background workers.
• Implement status updates (e.g., via Socket.io) as the job progresses.
• Add support for automatic retries on network failures.
