Last position:
Senior Software Developer with a Focus on UI/UX at vGen GmbH

The goal was to present complex relationships between IT systems, business processes, and departments in a way that is easy to understand and to support decision-making in the context of IT transformations.
The prototype combined data-driven analyses with guided questions and interactive visualizations. A central part was the integration of a RAG process to provide domain-specific EAM knowledge in context. The focus was on quick idea validation, user-centered interaction design, and the technical feasibility of a scalable overall concept.

About the technology
Identity control
Keycloak is an open-source identity and access management system. Companies use it to add single sign-on, login screens, user registration, password flows, and secure access for web apps, APIs, and internal tools.
Core features
- Single sign-on across connected applications
- OpenID Connect and SAML integration
- User federation with LDAP or Active Directory
- Role and group-based access control
- Branded login, consent, and account pages
Where it fits
Keycloak is common in portals, customer platforms, internal business systems, and regulated environments that need stronger access control. In Dusseldorf, it often appears in projects for industry, commerce, healthcare, and enterprise software teams that need clean identity flows without building them from scratch.
Tooling and skills
Strong professionals work with realms, clients, roles, mappers, tokens, and identity providers. They also understand OAuth 2.0, OpenID Connect, SAML, LDAP, reverse proxies, and container-based deployment.
When to bring help
Companies usually bring in freelance expertise when a rollout is blocked by messy identity architecture, migration work, or custom login requirements. That also applies when an existing Red Hat SSO setup needs to be aligned with Keycloak, or when teams need help with upgrades, security review, or integration debugging.
What strong experts deliver
- Clear realm and client design
- Secure, maintainable authentication flows
- Reliable federation and token setup
- Practical documentation for handover
- Support for rollout, testing, and troubleshooting
Frequently asked questions
Quick answers to the questions that come up most around Keycloak.
Keycloak is used to centralize login, user identity, and access control for applications and APIs. It helps companies add single sign-on, social or enterprise identity connections, and secure token-based auth without building every flow themselves.
Keycloak is often chosen when a team wants more control and self-hosting. Compared with Auth0 or Okta, it can fit better in environments that need on-premises deployment, deeper configuration, or tighter integration with existing infrastructure. It is usually a better long-term choice than custom login code when identity needs are growing.
A strong Keycloak specialist should know OAuth 2.0, OpenID Connect, and often SAML. LDAP, Active Directory, reverse proxies, Docker, Kubernetes, and basic security hardening are also common and useful.
For a simple single sign-on setup, a focused Keycloak expert may be enough. For migration, federation, or complex access rules, you want someone who has worked through token mapping, client configuration, and deployment issues before. The harder the identity landscape, the more practical experience matters.
Yes. Keycloak is used in containerized cloud setups as well as self-managed and on-prem environments. That flexibility is one reason it shows up in enterprise stacks with mixed infrastructure.
Look for clear realm design, clean client setup, and an explanation of why each flow exists. A strong Keycloak professional can discuss token lifetimes, user federation, logout behavior, and upgrade impact without hand-waving. Good documentation and a safe rollout plan are strong signs too.
Yes, most Keycloak work can be done remotely, especially configuration, integration, and troubleshooting. On-site time in Dusseldorf can help when access decisions involve security, infrastructure, or several internal teams. Many projects use a mix of both.
Keycloak and Red Hat SSO are closely related, and many teams still search for both names. If a project mentions Red Hat SSO, it often means the same identity patterns, configuration ideas, and migration concerns apply. A specialist should be comfortable with both the product history and the current setup.
