What I'm looking for

I seek a collaborative organization where I can provide executive-level administrative support, manage travel and events, improve processes, and support cross-functional teams for growth.

I am an Executive Assistant with over four years of experience supporting executive teams in corporate, research, and healthcare environments, primarily in Barcelona. I handle complex calendars, travel logistics, event coordination, procurement, invoicing, and database maintenance while working effectively with international and remote teams.

At Barcelonaβeta Brain Research Center I coordinated internal meetings, events, retreats, onboarding/offboarding, grant-support tasks, and managed procurement and vendor communications. At Hospital Santa Creu i Sant Pau and Kensington International Properties I supported executives with high-volume communications, budget tracking, reports and presentations, and recruitment-support activities.

I bring strong confidentiality, multitasking, and organizational skills, familiarity with tools like Microsoft Office 365, Dynamics 365, SAP, Factorial and Canva, plus conversational English and basic French—ready to contribute efficient administrative leadership to a collaborative team.
