Strong experience with HTTP, SOAP, REST APIs, and web services supporting rich-client and cloud-based applications.
Understanding of XML structures and data layouts to facilitate data exchange and integration between platforms.
Hands-on experience in application troubleshooting, debugging, root cause analysis, vulnerability remediation, and refactoring of legacy code.
Experience working with source control, build/deployment processes, and CI/CD practices.
Ability to work effectively across Agile development teams, business stakeholders, SRE, and other technology teams.
Strong analytical, problem-solving, documentation, and communication skills.

Nice-to-have / Secondary Skills

Experience or working knowledge of Java and the Spring ecosystem is an asset.
Familiarity with Java, Spring Boot, Spring MVC, and Java-based REST APIs/microservices.
