Hire a Celery developer who has debugged the failure modes in production
Celery + Redis is how I move slow work — inference, message processing, database writes — off the request thread. The hard part isn't the happy path; it's late acks, idempotency and what happens when a worker dies mid-task.
Problems I solve with this stack
A worker dies mid-task and the job silently disappears.
Late acknowledgements (acks_late) plus idempotent tasks, so a re-delivered task finishes exactly once. Written up in my FastAPI + Celery + Redis architecture guide.
Downtime means events were never enqueued, so the queue can't help.
A recovery job that backfills what was missed — the mechanism I built for WhatsApp document ingestion at Zuneko Labs.
Retries hammer a failing third-party API.
Exponential backoff, a retry cap, and a failed state someone actually monitors.
What you get
- Celery worker setup: queues, concurrency tuned to the workload, late acks.
- Idempotent task design with unique constraints at the source.
- Retries with exponential backoff and caps; dead-letter visibility.
- Recovery/backfill jobs for events missed during downtime.
- Monitoring guidance: what to alert on and what to ignore.
Frequently asked questions
Do you work with international clients?
Yes. I'm based in Pune, India, and work with teams in India and remotely worldwide. Communication is async-first with scheduled calls when needed.
What does an engagement look like?
A short call to scope the problem, a written scope (what will be built, what won't, and how we'll know it works), then small milestones you can review — with the code in your repository from day one.
Can you work with our existing codebase?
Yes. Most work is hardening, extending or extracting from existing systems rather than greenfield. I'll flag honestly where a rewrite isn't worth it.
Are you available for full-time roles too?
Yes — freelance, consulting and full-time conversations are all welcome. See the work-with-me page for how I work with clients and employers.
