Spring Boot API

About the Project

I developed this Spring Boot API, relying on PostgreSQL as the primary database. It is secured through OpenID Connect, leverages Hashicorp Vault for secret management, and is deployed on a self-managed Kubernetes cluster. Additionally, I designed and implemented a materialized path data hierarchy for use with Spring Data JPA, based on the Python Treebeard package.
