Experience

  • empir digital
    COO & Partner
    CONSULTING AND AUDITS
    February 2023 - Today (3 years and 4 months)
    Madrid, Spain
    Empir digital was born from the idea of offering a more personalized and specialized service, moving away from the 360 service of large agencies.
    Our expertise comes from the experience of having worked with clients from major sectors such as insurance, automotive, real estate, or fashion.
    This is why we define ourselves as a boutique agency specializing in Digital Analytics where the goal is to improve the performance of our clients' digital assets based on data.
    Our pillars are specialization in Digital Analytics, being at the forefront of the digital sector, and closeness with our clients.
    Once we correctly collect information from the assets, we can structure and create different dashboards and reports to visualize it in a practical and understandable way for anyone in the company, and then carry out analyses and improvement proposals (CRO).

  • MAPFRE ESPAÑA
    Malt logoOn Malt
    Data Manager (Pricing and Contracting Team)
    February 2023 - July 2023 (6 months)
    Madrid, España
    A very interesting and complex project given MAPFRE's large infrastructure.
    It has been a pleasure working with them; I have renewed until the end of the year due to the good performance of both parties during these 6 months, which has been a constant challenge at an operational and evolutionary level, with great learning of digital processes in a company that strives to be at the digital forefront, like MAPFRE.
    These projects are what motivate a consultant to keep learning and step out of their comfort zone.
    It has been a 360 project where I had to be involved in the detail of data collection (implementation, optimal data collection, validations, optimizations, etc.), managing and organizing a team of consultants who supported the development of all tasks to align with Mapfre's needs and timings.
