About Javier
I help companies automate repetitive work and build AI-powered workflows — so their teams focus on what actually matters.
With 6+ years of experience in data engineering and cloud architecture (GCP), I specialize in designing n8n/Make automations, AI agents (LLMs, RAG, document processing), and data pipelines that run reliably in production. My stack: Python, FastAPI, BigQuery, Airflow, Docker, and the full GCP ecosystem.
Previously Senior Data Engineer at Ebury (fintech, 3 years), Lead Data Engineer at StubHub International, and Senior Data Engineer at Twinco Capital — building ETLs, data warehouses, ML pipelines, and APIs at scale. Now CTO at Dekano, where I build AI products like Prisma (intelligent document processing).
What I deliver: n8n/Make workflow design and implementation, AI agent development (LLMs, RAG, MCP servers), data pipeline architecture (Airflow, DBT, BigQuery), API development (FastAPI, Cloud Run), and end-to-end automation of business processes.
MS in Artificial Intelligence (UPM) + BS in Computer Science (UAM). I write about Python and automation on Medium.
I typically deliver in days what others quote in weeks. Let's talk about what you need automated.
