About Us / Project Context

Our DBaaS (Database as a Service) team operates a central platform for automated provisioning and management of databases across multiple environments (e.g., AWS, GCP) and various DBMS (Oracle, PostgreSQL).

Current setup

- Database provisioning (create, modify, delete) is handled via CI/CD pipelines in GitLab
- A central Self-Service Portal serves as the user interface and triggers these processes
- The portal also provides features like billing, data maintenance, and integration with a central data inventory
- These additional functions communicate with other systems and portals via APIs

Technical background of the existing solution

- The current portal is based on an Oracle database with Oracle APEX frontend
- Core business logic is mostly implemented in PL/SQL within the database
- There is an existing Node.js/microservice layer, but it primarily acts as a forwarding layer to the database logic
- The existing platform is maintained and further developed internally , and this role will not be responsible for it

Technology / Stack

- Backend: Node.js (JavaScript)
- Frontend: Vue.js (preferred), React optional
- Database: PostgreSQL
- Containers & Orchestration: Docker, Kubernetes
- CI/CD: GitLab pipelines

- Scripting & Data Processing: Python
