Backend Developer - Background Jobs & Async Processing

Rosario, Argentina·4+ years·Spanish / English

Bio

I build systems that process things in the background reliably. 4 years working with job queues, scheduled tasks, and async workflows. I understand idempotency, retry strategies, and monitoring. Started in QA, moved to backend development to fix the bugs I was finding. My background jobs have proper logging, handle failures gracefully, and don't eat all the CPU. Systematic thinker who documents everything.
