Back-end Developer

I joined BBS (Bilgi Birikim Sistemleri) as a back-end developer intern in the late summer of 2023, working on enterprise back-end systems. My main work was building microservices with Java and Spring Boot, and wiring them up with real authentication: Active Directory sign-in and secured REST APIs using Keycloak (JWT and OAuth2) on top of Spring Security.

On the content side I worked with IBM FileNet for enterprise document management, including versioning and access control, and tested everything through Postman. I also built an Angular CRUD app on top of the back-end so the documents could be managed from a clean interface. The Document Management App in my portfolio came out of this internship.
