Back-end software engineer

I currently work for Grupo Carrefour Brasil as a back-end Javascript (Node) and Python (FastAPI) software engineer, responsible for design, develop and test solutions for loyalty programs and discount coupons issuing.

With a strong background on AWS and GCP , I develop cloud applications designed for the web. Out of the work, I'm always looking for new things to explore and ways to automate daily tasks.

My focus areas are Cloud, Microsservices and Serverless Applications, always applying industry-standards integration patterns.
