I've been a software developer since 2016, working on legacy and modern web applications, for the majority of this period working as a full-stack developer using the back-end Java with Spring Boot (and also Node, Go, Python, and C#, among others), and on the front-end, ReactJS (also JavaScript, and VueJS), creating restful APIs for scalable new applications and maintenance of current logic in different areas such as banking, customs transport, e-hub, and health and mental care.
Some of the technologies and architectures that I have the most knowledge of are Java, Spring Boot, Spring JPA, Spring Security, Hibernate, JavaScript, NodeJS, ReactJS, Kafka, Docker, Kubernetes, HTML5, CSS3, microservices, hexagonal, and clean architecture.
