HELLO!
I'm Gerai Castillo Serrano
I’m a creative from Barcelona who has always known that advertising was where I belonged. From the first time I noticed how a campaign could tell a story or how a logo could shape a brand’s identity, I was hooked on brand communication and creative strategy. I’m driven by ideas that connect, visuals that speak, and words that make brands feel human. Curious by nature and detail-oriented by instinct, I bring creativity, strategic thinking, and adaptability to every project. Outside of advertising, you’ll find me fueled by my passion for cars, music, and traveling, three things that constantly inspire my work and keep my creativity moving.
PROFESSIONAL EXPERIENCE
Creative Copywitter Internship
Muntañola Agencia Creativa
Barcelona, Spain
During my internship, I worked as a creative copywriter within a marketing and advertising environment, contributing to the development of advertising campaigns across multiple channels. I wrote and adapted creative copy for brand communications, ensuring consistency of tone, clarity of message, and alignment with strategic objectives.
Beyond copywriting, I supported the broader marketing process by preparing debriefs and internal briefs, designing and producing client-ready presentations, and assisting with translations and content adaptation for different markets. This role allowed me to gain hands-on experience in both the creative and strategic sides of advertising, collaborating closely with creative, account, and marketing teams to deliver cohesive and impactful campaigns.
