Acerca de Francisco

Does your team need a senior Data Engineer who can take a pipeline that's not scaling, or a Databricks cluster that's costing too much, and get it optimized and running reliably in production? That's what I do.
I've spent over 8 years building data platforms for companies like Mercedes-Benz, BBVA, and Telefónica, working across Python, PySpark, Databricks, Azure, and AWS. I currently lead a team of 15 (Data Engineers, Data Scientists, and Analysts), and have cut Databricks cluster costs by up to 40% through performance optimization and resource management, alongside designing a data quality framework that catches and blocks invalid data before it reaches the business.
What I bring isn't just code, it's translating a business problem into a data architecture that actually works, scales, and can be maintained by your in-house team without depending on me forever. I work equally well embedded in an existing team or owning a project end to end.

I can help with:
  • ETL/ELT pipelines in Databricks (PySpark, Delta Lake, Unity Catalog)
  • Migrating and modernizing data architectures on Azure (ADLS, Data Factory) or AWS (S3, Glue, EMR, Lambda)
  • Auditing and optimizing Databricks/Spark costs
  • Data quality and governance frameworks
  • Productionizing Machine Learning models alongside Data Science teams
  • Automating data workflows with CI/CD (Azure DevOps, Jenkins, Docker)

Fully remote, available for B2B projects across Spain and the rest of Europe. Professional English, used to working with distributed international teams.
