About Miriam

I have over 10 years of experience in digital marketing, working with platforms such as Google Ads, Meta Ads, LinkedIn Ads, Amazon, Google Tag Manager, Analytics, and Shopify. Additionally, I have managed email marketing campaigns and SEO optimization and auditing.

I enjoy having a global view of the business and understanding how each area contributes to overall success. My curiosity and passion for learning have led me to be in constant professional evolution. Currently, I am training in artificial intelligence, a tool that I consider key to continuing to innovate and improve efficiency in digital marketing.
