👨‍💻 About

🇺🇸 EN Backend developer at Banco Inter (Marketplace squad) and Software Engineering student at PUC Minas (graduating Dec 2027). I build REST APIs in Java with Spring Boot and Micronaut, integrating AWS services such as S3, DynamoDB, SQS, SNS and EC2. I also work with infrastructure as code (Terraform) and with observability and troubleshooting in production environments using Kubernetes, K9s, New Relic, Kibana and ArgoCD, always aiming to raise the reliability and operational efficiency of services.
