About Victor
Lead Data Engineer | Data Analyst
I design and operate end-to-end data infrastructure from raw ingestion to business-facing insights for organizations that need reliable, scalable data foundations.
I build data pipelines and Lakehouse architectures (Bronze/Silver/Gold) on AWS, GCP and Azure, using dbt, Airflow and cloud-native warehouses including Snowflake, BigQuery, Microsoft Fabric and DuckDB.
On the delivery side, I turn raw data into actionable KPIs and dashboards via Power BI, Looker and Tableau, and ship predictive models for segmentation, forecasting and anomaly detection directly into business workflows.
What sets my work apart:
- Fast grasp of business context, so technical decisions stay aligned with what actually matters to stakeholders
- Production discipline by default: testing, versioning, CI/CD and documentation, not afterthoughts
- DevOps/DataOps practices applied to data engineering, for pipelines that don't break silently
- Comfortable both building from zero on greenfield projects and untangling existing stacks with technical debt
I work across maturity levels: laying the first foundations of an analytics infrastructure, or taking ownership of an established stack and making it more reliable, more automated, and easier to extend.
Goal: turn your data into a measurable performance lever, with solutions built for your actual constraints and delivered fast.
