These are the advertising agencies I've freelanced for. I've worked as a creative director, copywriter, designer, art director, broadcast producer, and past-up person. Usually for project-based work which many ad agencies hire for specific campaigns or projects instead of hiring full-time employees.

My opportunities to freelance for agencies are also because they've been looking for various skills, including graphic & web designer for UA/UI, copywriting even though there is a growing dependency on Ai, art direction, as well as technical or strategic roles for social media and digital marketing allowing them to scale their workforce up or down based on project needs.
