About me

I’m a software architect focused on Identity & Access Management – with deep roots in DDD and distributed systems. Born and raised in Dortmund, Germany, I hold a diploma in computer science from TU Dortmund. I am partner and work as a consultant at CONCISO., helping teams build secure, maintainable systems with a clear architectural vision.

For over a decade, I’ve worked at the intersection of architecture, engineering, and strategic tech leadership. My foundation lies in Domain-Driven Design (DDD), the design of distributed systems, and building sustainable software architectures. More recently, I’ve developed a strong focus on Identity and Access Management (IAM), particularly using Keycloak to deliver scalable, secure solutions. That said, I don’t see myself as “just” an IAM specialist. I approach IAM as one part of a bigger architectural picture – embedded in systems thinking, business domains, and long-term maintainability.

Outside of work, I’m a proud uncle and godfather – and a wannabe guitar hero when time allows.

Public speaking

I speak at conferences, meetups, and internal events about software architecture, Domain-Driven Design, and Identity & Access Management with Keycloak. My talks blend strategic thinking with hands-on experience from real-world projects.

I'm also the founder of the DDD Rhein/Main Meetup, a community focused on collaborative learning in software design.

Curious what that looks like? Here’s a selection of my recent talks and sessions.

Writing

I also contribute articles to (online) magazines from time to time – covering architecture, DDD, and IAM topics.

Consulting

I offer system and software architecture reviews, technical analysis, and consulting — including Identity & Access Management solutions based on Keycloak — through CONCISO.
I also provide tailored workshops on topics like architecture, Domain-Driven Design, and IAM Whether you're modernizing an existing system or designing something from scratch, I help teams make better decisions with lasting impact.
