cesarfull-stack engineer2024 – present

CESAR is one of Brazil's top innovation centers, and it's where I spent most of my time on ESG Carbon, a platform ranked top 5 in ESGTech in Brazil that serves 140+ companies. I helped architect and ship it from zero with React, Next.js, TypeScript, Python and Django, turning a maze of GHG Protocol rules into a self-serve tool that cut manual reporting from 3 hours down to 5 minutes. These days I'm on a personal-finance fintech app, working end to end across a React Native app and a FastAPI backend on the Open Finance consent flow.

Avanade is a Microsoft and Accenture joint venture, and over three years there I went from intern to mid level building chatbot and AI products for large enterprise clients. I co-led the delivery of a production WhatsApp chatbot that drove 97k+ re-engagements in three months, cut response time by 44%, and lifted NPS by 5 points. I also built secure RAG assistants with LangChain, Azure OpenAI and embeddings.
