Bastian Cifuentes

I’m a results-driven bilingual Data Analyst and Fullstack Developer, focused on ensuring data integrity and turning complex datasets into actionable business intelligence. I specialize in Python, Django, and SQL, and I build secure, production-ready solutions for data-heavy environments.

In my Data Analyst role, I monitored and maintained large-scale datasets using data validation and classification protocols across global AdTech platforms. I streamlined data cleaning workflows and ETL pipelines to improve data accuracy and reduce processing latency, and I led QA initiatives by cross-referencing metrics to eliminate anomalies.

Earlier, I supported customers in technical and bilingual troubleshooting for financial and insurance software products, managing incident lifecycles via Salesforce CRM. Before that, I optimized production data processing and supply chain metrics with SAP ERP, analyzing inventory reports and operational KPIs to identify bottlenecks and drive continuous improvement.
