I'm looking for a senior backend role in Python or Node.js/TypeScript, building distributed systems—microservices, event-driven architectures, third-party integrations—with end-to-end ownership and a team where clean architecture and testing are habits. Remote from Spain, open to any country. Available immediately.

I build high-availability Python and TypeScript microservices, integrations and analytics platforms for advertising, media and HR tech.
SpainWhat I'm looking for
I built AscendGate at Ascend Makers: Python microservices on AWS EKS that validate campaign rules against 160+ per-channel constraints and integrate asynchronously with Meta, Google Ads, DV360 and TikTok, with zero duplicated campaigns despite daily retries. I also built AscendGX, from its ClickHouse analytics pipeline and API to its React dashboards.
Previously, I led the backend architecture for Movistar catalog tagging at Telefonica, a Python and Django service integrating large language models over Kafka. At Jobandtalent I introduced microservices and Hexagonal Architecture, cutting deployment time by 40% and improving system efficiency by 25%. I work test-first, reaching 100% unit and integration coverage on my last platform, and I've delivered products end to end across Python, Node.js, React, messaging and cloud infrastructure.
