About Gerardo

I design and build data platforms and backend services that companies rely on for critical business decisions.

With 4+ years of experience across energy trading, e-commerce, healthcare, and aviation, I specialize in:

→ Data pipeline design & optimization (dbt, SQLMesh, Airflow, Spark)
→ Backend API development (FastAPI, PostgreSQL, Python)
→ Cloud-native data platforms (GCP, AWS, Azure, Kubernetes)
→ Data quality frameworks & DataOps implementation
→ Technical audits and architecture reviews

Currently a Data Engineer at Axpo (European energy markets), previously at Thoughtworks — where I delivered data platforms for a top global airline, a major UK healthcare provider, and Europe's leading e-commerce company.

Certified Google Cloud Professional Data Engineer. MSc in Big Data & Analytics.

I take on freelance projects evenings and weekends: MVP builds, API development, pipeline optimization, data platform audits, and analytics setups. I scope clearly, communicate proactively, and deliver on time.

Available for remote work across Spain and Europe. Fluent in English and Spanish, intermediate Italian.
