What I'm looking for

I’m open to global opportunities to design and deploy scalable AI solutions with real-world impact.

At Concent Sistemas, I build intelligent laboratory systems with Python-based AI integrations and AWS cloud-native solutions. I engineered a serverless OCR and RAG pipeline that turns prescription layouts into validated data for exam identification.

I also built an agentic CRM workflow engine with LangGraph, Python, and FastAPI, using validated graph structures and streaming endpoints for real-time rendering. My work includes a Flutter app that connects laboratory patient data with AI-driven pipelines.

Previously, at Opctec, I integrated a Generative AI assessment engine into an educational platform and developed Laravel APIs and Vue.js interfaces. I’m open to global opportunities to design and deploy scalable AI solutions with real-world impact.
