I’m Rafael Chavantes, a Senior Full-Stack Engineer in São Paulo, focused on AI-assisted development and building production-grade software end-to-end. With 20+ years in technology—including nearly a decade at Cisco in complex enterprise environments—I’ve learned how to translate ambiguous business needs into reliable systems, from architecture and implementation to testing, debugging, and what ultimately ships. Since 2021, I’ve been delivering customer-facing and internal products across industries, often combining LLM-powered workflows (like RAG and guided decision systems) with deterministic validation and rules where accuracy and reliability matter. I use AI to accelerate execution, while staying responsible for the decisions that ensure the product works: defining the right solution, reviewing generated code, and choosing when not to use AI. I enjoy high-trust, autonomy-focused teams where clear goals and technical ownership lead to real outcomes.…I’m Rafael Chavantes, a Senior Full-Stack Engineer in São Paulo, focused on AI-assisted development and building production-grade software end-to-end.
