@jooguerreiro
I build backend APIs and deploy containerized applications with C#/.NET and Kubernetes.
PortugalWhat I'm looking for
I've built REST APIs, web applications, and Kubernetes deployments across internships at OneSource, Alidata, and Avante Coop.
At OneSource, I containerized applications with Docker, deployed them to Kubernetes, and reduced CPU resource requests by approximately 86% and memory requests by approximately 65% in a Kubernetes-native production workload. I also automated a machine-learning training stage by building a Kubeflow pipeline.
At Alidata, I developed the Pocket Manager website end-to-end and designed a Swagger-documented REST API to connect its frontend and backend.
My personal and academic work includes F1Ticket, a C#/ASP.NET ticket-management web app; a Java chess game with persistence; and SafetYSec, a Kotlin Android safety-monitoring app backed by Firebase. I'm open to remote and freelance work in backend development, APIs, and cloud/DevOps.
