Hi, I'm Guilherme Ribeiro, a Backend & DevOps Software Engineer with hands-on experience building CI/CD pipelines, containerized services, and zero-downtime deployment strategies. I have shipped mission-critical systems for aerospace (ESA) and have a strong foundation in NestJS, FastAPI, Docker, and PostgreSQL, focusing on reliability, automation, and scalable infrastructure. In my recent role as a Software Engineer Intern, I built real-time telemetry dashboards, established production-grade CI/CD pipelines, and designed rolling deployments with automated health checks and zero-downtime rollback. I enjoy turning complex problems into robust, maintainable systems and collaborating across teams to deliver value.…Hi, I'm Guilherme Ribeiro, a Backend & DevOps Software Engineer with hands-on experience building CI/CD pipelines, containerized services, and zero-downtime deployment strategies.
