Junior Data Engineer & Data Analyst | Computer Engineering Student (ESPOL, 8th semester)

I’m a Computer Engineering student at ESPOL, currently in my 8th semester, building a dual-track data career across Data Engineering and Business Intelligence. My strongest focus is designing reliable, reproducible data pipelines with validation, testing and automated delivery, while also translating analytical outputs into dashboards and business recommendations.

• Self-directed Data Engineering projects with ETL/ELT workflows, Pandera validation, automated testing and CI/CD quality gates.
• Analytics engineering foundations with SQL, DuckDB/dbt concepts, transformation layers and query optimization.
• BI/Data Analysis delivery through Power BI, DAX, KPI modeling, customer segmentation and revenue opportunity analysis.
• Portfolio-grade data products that connect raw data, validated artifacts, dashboards and clear stakeholder narratives.
