About David

Soy un profesional IT con más de 5 años de experiencia en administración de sistemas, DevOps y soporte de infraestructura.

Mi día a día gira en torno a automatizar todo lo automatizable: aprovisionamiento de infraestructura con Ansible, pipelines CI/CD con Jenkins, y gestión de plataformas contenedorizadas con Docker y Kubernetes/OpenShift. También me encargo de la administración y optimización de bases de datos (MongoDB, PostgreSQL, SQL Server), garantizando alta disponibilidad e integridad de los datos.

Tengo experiencia práctica en los tres grandes proveedores cloud (AWS, Azure y GCP), y en implementar soluciones de observabilidad y monitorización (Grafana, Prometheus, Dynatrace, Zabbix, Nagios) que permiten detectar y resolver problemas antes de que afecten al negocio. Trabajo siguiendo metodología ITIL, con foco en gestión de incidentes, cambios y mejora continua.
