What I'm looking for

I'm open to global and remote opportunities where I can build scalable web, data, and AI systems, improve infrastructure efficiency, and lead cross-functional delivery.

At Dentsu Creative, I build systems for Chevrolet dealerships that connect media, inventory, leads, sales, and customer experience across Brazil. I created a Python RAG API that transforms public competitor advertising data into queryable intelligence, moving from local Ollama and Llama 3.2 prototypes to Anthropic Claude for production analysis.

I improve the speed and economics of production platforms: I reduced duplicate-detection processing from 9.8 seconds to 1.2 seconds, cut Oracle infrastructure costs by 32%, and built a real-time inventory pipeline that removed a one-hour data lag and increased campaign conversion by 8%.

I've rebuilt legacy PHP applications in Laravel, led developers through integrations, and managed secure Linux and Docker environments. My work spans PHP, Laravel, JavaScript, Node.js, Python, databases, real-time systems, and cross-border delivery with teams in Brazil and Argentina.
