María José Guillamón

Administration and billing

Born in Cieza, better known to us in Murcia as the “Pearl of the Segura.” I grew up surrounded by peach orchards, puzzled by the local tradition of spitting olive pits. Naturally curious, I came to understand that what many see as a quirky (and somewhat unhygienic) game actually drives a big part of the economy in this wonderful place. That curiosity, combined with my knack for numbers and analysis, led me to study Business Administration and Management. After seven years of experience across various sectors, I consider myself a committed, responsible, and versatile professional. While I’ve always worked in administrative roles, my curiosity pushes me to learn as much as possible about every part of the company, and I often end up taking on all kinds of tasks. After a twist in my career that led me into HR, Cartonlab gave me the chance to return to my roots in administration—while also surrounding me with an amazing team. Methodical, organized, and detail-oriented, I do my part to streamline all the administrative processes so the rest of the team can keep doing their magic with cardboard.
