Available to hire
I am Samuel Camargo, a WebMethods Developer and Java Full-Stack Engineer based in Lisbon, Portugal. I design, develop, and maintain scalable, secure, high-performance web applications in cloud-native environments, delivering value to both desktop and mobile users. I work across the stack, with front-end technologies like React and Next.js and back-end services using Java and Spring Boot, always aiming for clean architecture, maintainability, and UX-aligned solutions.
I embrace modern DevOps practices: CI/CD, containerization with Docker and Kubernetes, and cloud deployments on AWS. I enjoy collaborating with product owners and designers to shape solutions that are robust, testable, and performant, while continuously mentoring peers and fostering a proactive, improvement-driven engineering culture.
