Consultant
Immowelt GmbH / AVIV Group
Consulting and optimization for transforming into cloud-only setup using AWS toolstack
Immowelt is running a hybrid setup of various Windows and Linux servers to provide their estate trade platform to enterprises and endusers all over Europe. To ensure maximum future IT capabilities, the customer wants to leave all local datacenters and systematically cut the two big monolith platforms into microservices running on AWS native tech stack. The complete AWS infrastructure is maintained with Terraform, versioned in Git-repositories and deployed with pipelines via gitlab, Jenkins or circle ci.
Wherever possible, the central Auth0 provider Okta is to be implemented, also in legacy applications.
On their journey to also provide a catching, seamless employee tech-stack, I supported them to develop some of their key decisions integrating MS Azure Intune and Okta. This way the (newly onboarding) users experience a seamless, automated path to get their new workstations up and running just where they want to work.
