Engineering teams running long-lived AI workflows, financial batch jobs, or high-volume webhook processing frequently search to hire a freelance Celery, Temporal.io & BullMQ distributed task queue programmer. I am Aldian Fazrihady, a Senior Freelance Backend & Full Stack Programmer available via Upwork.
Core Distributed Queue & Durable Execution Capabilities
- Production Celery & Redis/RabbitMQ Architecture: Designing priority routing queues (`acks_late`, `prefetch_multiplier=1`), dead-letter queues (DLQ), exponential backoff retries, and Flower/Prometheus observability for Python/Django/FastAPI workloads.
- Temporal.io Durable Workflows (Python, Go, TypeScript): Building fault-tolerant, multi-step saga workflows that survive worker restarts, API rate limits, and third-party outages without losing state or duplicating side effects.
- BullMQ & Node.js Job Pipelines: Implementing parent-child flow dependencies, concurrency rate limiters, and graceful shutdown handlers for TypeScript microservices.
Frequently Asked Questions
Can a freelance programmer fix memory leaks or stuck tasks in our Celery workers?
Yes. I configure `--max-tasks-per-child`, `--max-memory-per-child`, soft/hard time limits, and idempotent database locks so stuck tasks never exhaust worker pools.
How can we hire you for Celery or Temporal.io architecture?
