Sobre mí
I help businesses automate repetitive tasks, process datasets, and build reliable Python-based ETL workflows.
I combine data engineering with 10+ years of business optimization experience. I specialize in cost-efficient solutions; my Cyber-Trace project achieved a 90% reduction in compute costs.
Main focus areas:
- Python-based automations
- SQL and data processing (Pandas/Polars)
- API integrations
- Azure and Microsoft Fabric
I prioritize clear communication, documentation, and a security-first approach (NIS2 and GDPR).
