If you want to know the history of Guille's smile we tell you all about it in this podcast from the sensational "In the Mind of an Engineer" channel from Alvaro Buitrago Alvarez.

We recommend that you skip the first half hour or more, since the guest is especially soporific 🤣 .

Thanks a lot Alvaro Buitrago Alvarez, for giving us a voice, for your support and for having even gotten us new opportunities at the hands of Lucia Buitrago Alvarez
