SOFTWARE ENGINEER | JAVA, BACKEND & CLOUD

Yassine Ouabou

Building secure APIs and reliable backend systems.

I’m Yassine, a software engineer working across Java, Spring Boot, Oracle ORDS, and cloud technologies. I turn complex requirements into thoughtful, dependable software.

01 ABOUT

Behind the code,
a curious engineer.

My foundation is software engineering. My focus is what makes an application work well beneath the surface: clear APIs, secure access, and reliable backend systems.

Through internships at Oracle R&D Morocco, AHDIGITAL, and Alias Informatique, I’ve worked across identity and access management, event-driven services, cloud infrastructure, and full-stack applications. I bring that end-to-end perspective to every problem I work on.

Explore the work: Modernizing the ORDS sample application

MY CONTRIBUTIONS · Research Assistant Intern

  • Migrated authentication from Auth0 to Oracle IAM, implementing OAuth 2.0, OpenID Connect, JWT authentication, and scope-based access control for protected REST endpoints.
  • Migrated local ORDS configuration to OCI Database API Gateway Configuration Service, using Cloud as the metadata source.
  • Added an ORDS Sample App Codex Skill to Oracle’s GitHub repository for OCI CLI environment bootstrap, validation, troubleshooting, and migration of ORDS PL/SQL definitions to OpenAPI specifications.
  • Investigated and fixed issues across Java and JEE components, with JUnit and integration testing. Conducted performance and memory regression testing using Grafana k6.

OUTCOME

Updated the sample application’s identity integration, moved configuration to OCI, and improved developer setup and migration workflows.
