I’m a Data Analyst and Python Developer with 4+ years of experience building analytics and automation solutions for companies (transportation, e-commerce, and scientific projects). I create reports and dashboards in Power BI/Tableau, and design SQL data models (CTEs, window functions) on MySQL/PostgreSQL/MongoDB, focused on business decision-making (KPIs, time intelligence, segmentation, cohorts, funnels, and performance).
Additionally, I develop ETL/ELT pipelines with Python, Pandas, and PySpark to clean, standardize, and consolidate data from Excel/CSV/JSON/APIs/PDF/Word, with quality control, traceability, and documentation. I’ve processed 1,000+ files in real projects and optimized workflows, reducing operational time by up to 80%. I deliver reproducible results with clear metrics and smooth communication in Spanish and English.
