About Nawal

Software engineer with 9 years of experience, specializing in application security and identity management (IAM).

I work on projects involving Keycloak, OAuth2/OIDC, SAML, and SSO integration in JAVA/Spring Boot architectures.

My profile covers the entire back-end stack (Java, Spring Boot, Wilfly/JBoss, Oracle) and front-end (Angular), with particular expertise in advanced Keycloak configuration: identity federation, custom authentication flows, realm management, REST API security.

My preferred area is interoperability between heterogeneous systems: SSO integration, identity federation, API security, and inter-application exchanges.
