Acerca de Mar

Vibe Coder passionate about scaling businesses through data, automation, and creativity.

My career is rooted in a background as a Marketing and Partnerships Manager. A key highlight was leading the end-to-end execution of the first "Latin Data Week," which generated an 807% ROI.

Since 2024, I have pivoted my focus to Data Analytics and AI Automation. As a freelancer, I deliver data-driven solutions including:

Smart Customer Support: Developed an AI-powered chatbot for a marketing agency.

Customer Retention: Built an automated reminder system to increase the Lifetime Value (LTV) for an automotive company.

Conversion Optimization: Designed a high-performing Go-to-Market landing page for an e-commerce brand.

Beyond technical delivery, I am an experienced educator. I have taught Data Analytics and Growth Marketing to over 150 international students, including executive-level managers at Uber.
