Guillermo Gavilán

I joined the company in 1999 in the intelligent network development area of Telefónica Móviles, just when we were preparing for the dreaded "Y2K". At that time it seemed that all the machines were going to go crazy with the change of digits, although logically this was not the case, and hundreds of people worked to ensure that this did not happen. In this centenary year I personally celebrate my "silver jubilee" in this company. My career has always been linked to the world of technology and digital transformation.

I believe that at Telefónica the great constant over time has been continuous change. I have had the opportunity to experience first-hand the convergence of the different fixed, mobile and data networks; the unification of customer management, customer service and billing systems and also the incredible transformation of our advanced analytics and business intelligence capabilities, all of this accompanied by a constantly changing organisation and excellent colleagues.
