About Juan

Analista de Datos Junior con un año de experiencia en equipos de Operaciones en dos startups de rápido crecimiento. En ambas compañías he utilizado SQL para la extracción de datos habiéndome especializado en esta herramienta en mi equipo actual. También he utilizado extensivamente Microsoft Excel y Python para el análisis de los datos extraídos y para la presentación de las conclusiones.

Nunca doy nada por hecho y siempre intento ir más hayá de lo que se puede ver a primera vista en los datos. Tengo buena capacidad de análisis y buen ojo para el detalle. Mi punto fuerte es la manipulación, limpieza y análisis de datos para poder sacar conclusiones que ayuden a tu negocio a entender mejor a tus clientes/usuarios y mejorar la eficiencia de tus procesos.
