Soy consultor senior de inteligencia de negocios con más de 10 años de experiencia diseñando e implementando soluciones BI que ayudan a las empresas a tomar decisiones basadas en datos.
Me especializo en QlikView, Qlik Sense y Qlik Cloud, desarrollo de dashboards interactivos, modelado de datos, scripts de carga (ETL), extracción de información de diversas bases de datos (SQL Server, Oracle, etc.), definición de KPIs e indicadores de gestión, y soporte continuo (mantenimiento, entrenamiento y optimización).
Sectores de experiencia:
• Control de gestión y finanzas
• Banca y servicios financieros
• Seguros
• Servicios aeronáuticos
• Salud
• Retail y logística
• Importación y distribución
Mi objetivo es siempre el mismo: entregar soluciones claras, confiables y de alto impacto que permitan monitorear operaciones en tiempo real, optimizar procesos, reducir costos y mejorar márgenes.
Busco proyectos puntuales o de duración definida (desarrollo de aplicaciones Qlik, mantenimiento de entornos existentes, migraciones QlikView → Qlik Sense -> Qlik Cloud, creación de dashboards, NPrinting, soporte ad-hoc, etc.).
Abierto a trabajo remoto desde Zaragoza o mixto.
