5+ years' professional software development experience, with strong Java experience. Strong hands-on experience with Java, Spring Framework and Spring Boot. Solid experience with JPA and Hibernate and ideally Micronaut. Strong understanding of Object-Oriented Design and software engineering principles. Experience building Microservices and/or SOA-based solutions. Strong API and integration experience across REST and SOAP. Experience with application security including JWT and SSL/TLS.
