About Cristina

I am a systems engineer with over 8 years of experience in digital identity, security, and systems administration in enterprise environments.

In my day-to-day, I work with tools like Okta, Microsoft Entra ID, and Microsoft Purview, so what I offer is not theory, but real experience applied in organizations with demanding security requirements.

I can help you with the implementation and administration of Okta, configuration of Entra ID with conditional access and MFA, data loss prevention with Microsoft Purview, process automation with PowerShell and Jenkins, and advice on cloud migrations.

I work well with companies that do not have a large technical team but need things done right from the start. I am direct, I like to fully understand what the client needs before starting, and I deliver documented and clean work.

Available for part-time projects from the United Kingdom.
