Hi, I'm
based in Madrid 🇪🇸
I build production data pipelines and AI agents. Python, PySpark and SQL on Azure, GCP and AWS, focused on Lakehouse architectures, orchestration and LLMs.

Experience
Jun 2026 — Present
Data team within the Supply Chain area of the Telefónica project. Design and operation of ETL pipelines for materials supply and replenishment, integrating heterogeneous sources (REST, Oracle, PostgreSQL) with reliable, traceable data delivery in production. Orchestration with Prefect, CI/CD with Jenkins and deployment on Azure with Docker.
Apr 2025 — Jun 2026
Design and implementation of transformation and orchestration processes over Lakehouse architectures. Ingestion and ETL pipelines with PySpark, SQL and Python orchestrated with Apache Airflow and NiFi on GCP, Azure Databricks and Cloudera. Layered modeling (raw / silver / gold) with Parquet and Delta, in direct collaboration with business teams.
Jan 2024 — Apr 2025
Services and data processes for the travel booking ecosystem. Microservices in Scala/Spark, Python and C# on Azure with CI/CD on Azure DevOps; REST and gRPC APIs with MongoDB and PostgreSQL in high-availability environments; and frontend with React, TypeScript and GraphQL for internal management tools.
Jul 2023 — Dec 2023
Reservations system development team: maintenance and evolution of backend services, and first exposure to distributed architectures and Azure cloud environments.

About
Data & AI Engineer with end-to-end experience in data engineering, analytics and applied AI. Master's in Big Data & Data Engineering from Universidad Complutense de Madrid and a Bachelor's in Computer Engineering from the University of the Balearic Islands.
I've built ingestion, transformation and orchestration pipelines with Airflow and Prefect on cloud architectures (Azure, GCP, AWS), integrating heterogeneous sources for real use cases in telecommunications, travel and bookings. I also have full-stack experience (React, TypeScript, GraphQL) alongside the data work.
I'm especially interested in productionizing generative AI solutions, Lakehouse architectures and scalable analytics layers. And when a problem grabs me, I turn it into a product: that's how LeadForge and Margeny were born.
