About Me
Backend Developer with 8+ years of experience building data pipelines, microservices, and cloud infrastructure. Based in Valencia, Spain.
I’ve worked across domains that demand reliability at scale: IoT platforms processing thousands of device connections, fleet management systems ingesting large volumes of vehicle data daily, and multi-project backend portfolios with full ownership from infrastructure to deployment.
What I bring to a team
- Microservices migration experience — Led the transition from monolith to microservices on a LoRaWAN Network Server, improving scalability and independent deployment.
- Data pipeline design — Built daily ingestion pipelines processing Big Data for enterprise fleet clients, integrating with reporting engines and alerting systems.
- Infrastructure ownership — Design and manage AWS infrastructure with Terraform (IaC), optimizing for performance and cost.
- Mentoring & code quality — Active in code reviews, architectural discussions, and promoting best practices across teams.
