Nice-to-Haves

• Experience with Azure services (Container Apps, Key Vault, Entra ID) and GitHub Actions.
• Experience turning spreadsheet-based business models into code.
• Experience with versioned or effective-dated data.
• Experience generating PDF documents from application data.
• Consulting or client-facing experience.

Why Join Us?
