What I'm looking for

I'm looking for a remote back-end or full-stack role with Python (FastAPI or Django), where I can build and ship APIs and data-driven features, learn from experienced engineers through code reviews, and grow into a strong back-end engineer.

I'm a junior Python back-end developer based in Brazil (UTC-3), looking for remote back-end or full-stack roles. I'm also finishing a Computer Science degree (2027).

I've built and deployed a personal library platform with a FastAPI API, React + Vite front end and PostgreSQL on Supabase. It integrates Google Books, Resend and Supabase Storage, with authentication, file uploads, pagination, migrations and OpenAPI documentation.

I work with asynchronous FastAPI, SQLAlchemy 2.0, Redis (cache-aside), JWT and OAuth2 security, and Docker Compose environments running APIs, PostgreSQL and Redis.

Before focusing on development, I spent 4+ years in data quality at Lett Digital, later acquired by Neogrid, in a fully remote role. I analyzed around 1,000 SKUs daily for Nestlé, Ambev and PepsiCo catalogs, coordinated a six-person setup backlog, and helped resolve a critical Nestlé catalog incident within the same day.
