About Carmen

Soy ingeniera de datos con enfoque en Cloud y DevOps. He operado con pipelines escalables en batch con Python y Spark (PySpark), orquestados con Airflow y automatizados mediante GitLab CI/CD sobre AWS (S3). He trabajado en streaming y análisis en tiempo real con Kafka y Flink, y construí ETLs con NiFi. Integro monitorización y observabilidad con Prometheus/Telegraf/InfluxDB, Grafana y ELK (Elasticsearch/Kibana), y también desarrollo soluciones en Azure y Power BI cuando el proyecto lo requiere.
