Rockstar🎓
Top SchoolFernando Saraiva is a pragmatic back-end developer with about six years of experience building IoT-enabled industrial systems, APIs and real-time web interfaces, currently focused on backend engineering and Go. He has deep hands-on experience from microcontroller C++ code on the factory floor to TypeScript/Node.js APIs, PostgreSQL/MongoDB data layers, WebSockets for realtime, and orchestration with Docker and RabbitMQ. Fernando contributes to prominent open-source projects—helping Kubescape improve PDF reporting by upgrading and integrating the maroto library—and maintains his own initiatives like OpenIoT to simplify device observability and deployment. At previous roles he owned end-to-end solutions from cloud architecture to CI/CD pipelines, and today he’s sharpening skills in observability and microservices while expanding his footprint in the Go community. Notably, he has implemented PDF generation directly from JSON for APIs and automated line-height and multi-style text handling in a popular Go PDF library.
