Data Analytics | Business Intelligence | Microsoft Certified Data Analyst Associate ✔️| Analista de datos✔️.

Con más de 9 años de experiencia en análisis de datos y soluciones de Business Intelligence, me especializo en el diseño e implementación de proyectos centrados en el ecosistema Microsoft y tecnologías complementarias. Mi enfoque principal está en Power BI, Power Pivot, donde he desarrollado dashboards dinámicos y visualizaciones avanzadas que transforman datos complejos en información clara y estratégica.

Domino el modelado dimensional (estrellas y copos de nieve), creación de modelos Tabulares y Multidimensionales, y el uso avanzado de DAX y Power Query para optimizar análisis y rendimiento. Además, tengo experiencia en la integración de Power BI con diversas fuentes de datos, tanto on-premises como en la nube, utilizando plataformas como Azure y bases de datos como SQL Server, Postgres y MySQL.

En el ámbito de procesos ETL, he trabajado extensivamente con SQL Server Integration Services (SSIS) y Microsoft Fabric, desarrollando pipelines robustos y escalables que alimentan modelos analíticos. También manejo SQL avanzado para consultas complejas y optimización de bases de datos.

Además de Power BI, mi experiencia abarca toda la suite de Microsoft Power Platform, incluyendo Power Apps y Power Automate, lo que me permite crear soluciones empresariales automatizadas e innovadoras. Estas herramientas han sido clave para mejorar la eficiencia operativa y acelerar la toma de decisiones en los proyectos en los que he participado.

Mi habilidad para combinar herramientas de análisis, modelado de datos y automatización empresarial me posiciona como un especialista integral capaz de aportar soluciones estratégicas y sostenibles en entornos dinámicos y de alta exigencia tecnológica.
