At ContaAzul, I architect and deliver AI-powered SaaS applications for enterprise customers using Python, FastAPI, React, Next.js, and TypeScript. I build RAG platforms, AI inference services, workflow orchestration, secure APIs, and conversational AI interfaces.

I've reduced average response latency by more than 35% through database tuning, caching, background processing, and prompt optimization. I deploy containerized applications on AWS with Docker, Kubernetes, GitHub Actions, and automated CI/CD pipelines.

Previously at Arquivei, I led development of enterprise cloud applications and improved API response times by approximately 30% through indexing, query optimization, and service refactoring. I also established reusable UI component libraries, frontend standards, architecture reviews, and mentoring practices.

My background includes customer-facing web platforms at Conexa, where I built APIs, analytics, search, payment integrations, and responsive React experiences. I enjoy partnering with product, design, data, and engineering teams to turn business requirements into reliable software.
