Stefan Voorbij — Senior Database Administrator

Hi, I'm Stefan 👋

I'm a Senior Database Administrator working with Oracle, PostgreSQL and Linux.

My main interest is turning operational database work into processes that are repeatable, controlled and auditable — especially around patching, migrations, security and automation.

🔧 What I work with

  • Oracle Database — 19c, RAC, ASM, Enterprise Manager
  • PostgreSQL — administration, migrations and performance
  • Oracle Linux
  • Automation — Shell, Python, Ansible and AWX
  • Security & compliance — OpenSCAP / STIG
  • Database patching — validation, approval flows and evidence

🚀 Featured projects

Oracle Patch Guard

A controlled, approval-driven framework for Oracle Database patching.

PRECHECK → PLAN → APPROVE → APPLY

Highlights:

  • validated local patch media
  • cryptographic approval and integrity checks
  • fail-closed execution
  • multi-target and OEM integration
  • regression testing and audit evidence

OpenSCAP STIG Compliance Dashboard

Reporting and dashboard tooling for OpenSCAP and STIG compliance on Oracle Linux.

PostgreSQL 11 → 16 migration

Notes and tooling around PostgreSQL migration from version 11 to 16, including Oracle Linux platform migration.
