About me 🚀

I'm a Senior Software Engineer specialized in backend, cloud infrastructure, and distributed systems, with strong experience building production-grade platforms in high-traffic environments.

I usually work close to product, infrastructure, and stakeholders, helping teams design systems that are:

  • scalable
  • observable
  • secure
  • maintainable over time

My background combines hands-on backend engineering, DevOps/SRE practices, and technical leadership in real-world projects.


Core expertise 🧠

  • Backend architecture with Python & Django
  • API design (REST-first, pragmatic, scalable)
  • Async & background processing (Celery, Redis, queues)
  • High-traffic systems & performance tuning
  • Cloud-native infrastructure & CI/CD
  • Pragmatic DevOps (not buzzwords)

Tech stack 🛠

Backend & APIs

Python Django Django REST FastAPI Starlette

Async, Messaging & Jobs

Celery Redis

Databases & Search

PostgreSQL MySQL MongoDB ElasticSearch

Infrastructure & DevOps

Docker Nginx Terraform GitHub Actions Sentry

Networking & Security

What I’m focused on now 🔍

  • Designing robust backend architectures for long-lived products
  • Improving observability, reliability and performance
  • Scaling systems without over-engineering
  • Applying AI/LLMs responsibly in real production systems
  • Acting as a technical reference for teams and products

Currently 📍

  • 🇪🇸 Based in Barcelona, Spain
  • 💼 Working in media & high-traffic digital platforms
  • 🧩 Combining backend engineering + infra + product thinking
