Brazil

Message

At the Artificial Intelligence and Dedicated Architectures Laboratory, I restored GitHub Actions pipelines across three repositories, enabling automated daily deployments in under five minutes. I also introduced release workflows and set up monitoring and daily PostgreSQL backups for the CEDROROSA Project.

At Baiao, I provisioned a development server with Terraform and Ansible, reducing baseline setup from 1–2 hours to 5–10 minutes. I also load-tested API endpoints and co-developed NestJS modules and Angular payment flows. As a Teaching Assistant for Systems Administration, I explain infrastructure to developers, clients, and students.
