full-stack engineer · fiveyears · ai & saas
I build and ship web products, end to end, from the data model to the pixel, and I've been at it for about five years across startups and bigger enterprise teams.
Right now I'm at cesar, where I built ESG Carbon, a platform used by 140+companies, and these days I'm on a personal-finance fintech app across React Native and a FastAPI backend. Before that I spent three years at Avanade, the Microsoft and Accenture joint venture, shipping chatbots and RAG-based AI products for big enterprise clients.
On the study side, I have a BS in Information Systems from Descomplica, and I'm currently doing a postgrad in AI Engineering at FIAP, digging into LLMs, generative AI, RAG, LangChain and the whole modern AI stack.
When I'm not working I like to contribute to open source, play a bit of guitar, ukulele and piano (badly, but happily), and I spend a good chunk of my free time at the gym.
Five years of work.
One academic track.
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 architected and shipped 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.
A postgrad certificate in AI Engineering that covers pretty much the whole modern AI stack, from machine learning fundamentals and computer vision to LLMs, generative AI, prompt engineering, fine-tuning, RAG and LangChain. I should wrap it up around march 2027.
My bachelor's in Information Systems, finished in december 2025. It covered a bit of everything, from data structures, databases and cloud computing to software design, AI algorithms and data science, which gave me the base to work across the whole product lifecycle.
What I reach for.
Three things I do
when I'm not shipping.
Music
I play guitar, ukulele and piano, honestly not that well, but I have a great time doing it. Some of it even ends up as background noise while I code.
Gym
Lifting is my daily reset button, and it's pretty much non negotiable. I train five times a week, mostly compound lifts.
Films & TV
I'm a big fan of Mike Flanagan and Game of Thrones, and my comfort show is Modern Family on an endless loop. Always up for recommendations.
Open source.
A year in commits.
My GitHubactivity over the past year. It's a rough snapshot of the side projects, open source PRs and weekend tinkering that don't really fit anywhere else.
