Precious Agaga
Senior IT Systems Engineer
Architecting resilient digital foundations for enterprise-scale organisations, currently at Cresta AI in Berlin.
I am a German citizen who has spent the better part of a decade building and running infrastructure for organisations that cannot afford for things to break. My work sits at the intersection of cloud infrastructure, identity governance, and enterprise automation. Right now I am at Cresta AI in Berlin, and I am open to remote and hybrid opportunities where the work is genuinely complex.
What I Do
Most of my work involves making things run reliably at scale without requiring a team of engineers to babysit them. That means writing infrastructure as code with Terraform, building automated provisioning pipelines on AWS, and designing identity systems in Okta and Azure AD that hold up under real conditions. I work in Python and Bash when I need to, and I have built more Slack-based automation workflows than I can count.
On the endpoint and device side, I have managed fleets of over 1,200 devices across JAMF Pro, Kandji, and Intune. On the security side, I have implemented zero-trust architecture and handled SAML and OAuth2 integrations across a range of SaaS platforms. The through line in all of it is removing manual steps that should not exist.
How I Got Here
I started at the Cisco Networking Academy in Nigeria, which gave me a real foundation before anything else. After moving to Germany, I completed a B.Sc. in Business Informatics at the Technical University of Applied Sciences Wildau, studying entirely in German. That combination, engineering fundamentals plus business context plus a second language at professional level, shaped how I approach problems.
The companies I have worked at cover a lot of ground: HealthTech at Dr. Smile and Ada Health, energy infrastructure at RWE, and high-scale fintech at Trade Republic. Each environment had its own constraints and pressures. That range is one of the more useful things I can bring to a new organisation.
Certifications
I hold certifications as an AWS Certified Cloud Practitioner, Atlassian Certified Expert, Okta Certified Professional, HashiCorp Terraform and Vault Associate, and CompTIA A+. I work in English at C2 level and German at C1, which means I can lead technical discussions, write documentation, and navigate bureaucracy in both languages without a translator.
