About Jose

En mi sitio web joseriesco.com podrás encontrar mis proyectos actualizados

Mi carrera en datos comenzó en la cotizada alemana Bechtle, donde lideré la digitalización del departamento de operaciones. Automatizé procesos con Python, Power Automate y VBA, y desarrollé reportes en Power BI para mejorar la toma de decisiones.

Luego, en Mscope, empresa enfocada en herramientas para fondos de inversión, gestioné bases de datos, creé ETLs complejas y modelos automatizados para optimizar la gestión de fondos. Trabajé con AWS (Lambda, S3, Step Functions, RDS, EMR) e integré APIs con Postman y Python para mejorar el procesamiento de datos.

También desarrollé una web automatizada con Django y Selenium, aplicando HTML y CSS.

Me especializo en automatización, análisis de datos y optimización de procesos. Si buscas mejorar eficiencia y aprovechar datos, ¡hablemos!

My data career started at the German-listed company Bechtle, where I led the digitalization of the operations department. I automated processes using Python, Power Automate, and VBA, and developed Power BI reports to enhance decision-making.

Later, at Mscope, a company focused on investment fund tools, I managed databases, built complex ETLs, and automated models to optimize fund management. I worked with AWS (Lambda, S3, Step Functions, RDS, EMR) and integrated APIs using Postman and Python to improve data processing.

I also developed a fully automated web platform with Django and Selenium, applying HTML and CSS.

I specialize in automation, data analysis, and process optimization. If you're looking to boost efficiency and make better use of your data, let’s talk!
