Back-End Software Engineer at Stagwell Marketing Cloud building LLM tools for marketing content and campaign risk analysis.

Brazil

Message

At Stagwell Marketing Cloud, I develop backend solutions and LLM-integrated tools for marketing workflows, including campaign text and image generation and editing. I also developed a COSO Framework-based platform that automates marketing-project risk analysis in spreadsheets and provides LLM-driven recommendations.

Previously, at Imperium Markets, I developed backend solutions for banking companies and led applied LLM research and proof-of-concept projects. I also cut search query execution times by over 80% across critical endpoints through Django ORM optimization and Redis integration.
