Hi, I'm Jesús Caballero 👋

Senior Backend Engineer · Python 🐍

I build reliable backend systems for high-throughput APIs, asynchronous workloads, event-driven architectures and data-intensive applications.

My main focus is Python, with experience across Django, FastAPI, Kafka, Celery and AWS. I care about simple architecture, meaningful tests, observability and software that remains maintainable as systems and teams grow.

🧠 How I approach engineering

• Keep it simple — prefer clear, maintainable solutions over unnecessary complexity.
• Build for production — reliability, observability and failure handling are part of the design.
• Test with purpose — meaningful automated tests that give teams confidence to move fast.
• Design for change — clear boundaries and pragmatic architecture that can evolve with the product.
