  Data engineer / backend developer

  I redesigned and implemented ETL pipelines in Python/BigQuery, improving data throughput by 40% for real estate data processing. I also designed an automated backup system using React and NestJS, reducing data loss by 90%. I optimized BigQuery data models for Power BI dashboards, enhancing data accessibility and visualization. Leading AWS-to-GCP infrastructure migrations, I optimized costs and improved system scalability using Cloud Functions, VMs, and Cloud Run. I developed a predictive cost monitoring system in GCP, reducing expenses by 20%.Additionally, I led the development of a Django application with a REST API for the Fiscalía General de la Nación, integrating language models (LLMs) for the simultaneous analysis of structured and unstructured data. This accelerated report generation by 40%, benefiting over 10 investigators. I also created a Django-based gallery for managing over 1 TB of unstructured data connected to a Hadoop cluster, applying design patterns to reduce search and indexing times by 50%, thus enhancing accessibility for critical investigations.
