AI speeds up development, but only on a solid foundation. I bring both together: 20+ years of software architecture and engineering, including large enterprise landscapes, and hands-on experience putting AI agents to work in development teams and products.

Focus areas
• Agentic Engineering: Establishing Claude Code, Codex & co. as a shared way of working in teams, backed by tests, CI, independent reviews and clear boundaries, so agents deliver verifiable results instead of claims.
• AI in products: RAG, agents with tools and MCP, evaluation and operations, from first idea to production.
• Software architecture: Event-driven architecture, Kafka, Domain-Driven Design and Event Modeling. Systems that stay understandable, operable and evolvable.
• Modernization: Replacing and integrating legacy systems step by step without putting operations at risk.
• Coaching & workshops: Remote or on-site, for development teams and decision-makers (Beyond Bits Academy).

I look at product decisions, architecture and code together. I advise, design and implement hands-on with the team. People over processes: I lead by example and make teams stronger instead of dependent.

Projekthistorie

Migration of a legacy university management system (architecture consulting, migration, coaching)

Sonstiges

250-500 Mitarbeiter

As a Software Architect at a leading distance learning university, I provided architectural guidance for their new university management system. 

My focus was on improving platform maturity by implementing standards, architecture principles, and making key architecture decisions. I introduced event-driven architecture concepts to ensure delivery and order guarantees, consistency, and facilitated the migration and solution design of new modules. By introducing distributed tracing, I improved platform observability and enabled quicker issue resolution. I mentored multiple teams on Domain Driven Design and Clean Code, while also advising product owners and conducting event stormings to analyze business processes and identify bounded contexts.

Scalable high-traffic multi-purpose streaming platform (architecture consulting, coaching)

Medien und Verlage

500-1000 Mitarbeiter

As a Software Architect for a high-traffic multi-purpose streaming platform, I focused on streamlining business processes and decoupling systems via asynchronous communication. 

My most significant achievement was transforming horizontal layers into vertical domains, navigating organizational changes and seamlessly coordinating multiple project teams into adopting the new structures. In addition I successfully led a development team in establishing cross-team GraphQL best practices, and rolled out GraphQL Federation as a project-wide replacement solution for a collaborative public API.

Multi-tenant system for an OTT streaming platform (full stack development, architecture consulting)

500-1000 Mitarbeiter

The goal of this project was to create a highly scalable and efficient multi-tenant backend and frontend system for an OTT streaming platform that could handle a large volume of concurrent users and video streams.

As a Software Engineer, I focused on the conception and development of the platform and the strategic planning of migrating the API architecture to GraphQL as an alternative to the BFF pattern. I also provided team coaching in areas such as clean code, TypeScript, and Node.js. Further I optimized the developer experience by developing tooling like a RxJS resiliency library.

Event-based backend system for a podcast streaming platform (full stack development)

Medien und Verlage

5000-10.000 Mitarbeiter

As a Software Engineer, my responsibility was to design and develop an event-based backend system for a podcast streaming platform. In addition to requirements engineering and documentation, I built the system infrastructure using infrastructure as code techniques. This allowed for efficient and automated provisioning, configuration, and management of the backend system. Choosing an event-driven approach for the platform allowed for real-time processing and handling of incoming podcast streams, ensuring high performance and reliability. Some fun stuff around image processing gave this project the additional spice.

Modular system architecture for sales interfaces (architecture consulting, development)

Versicherungen

1000-5000 Mitarbeiter

As a Software Architect, I was responsible for the conception and implementation of a generic, microservice-based front-end architecture for sales interfaces. I also played a key role in coaching and rolling out OpenShift, a container application platform, which allowed for efficient and flexible deployment of the front-end system. I created reusable base images and Kubernetes deployment templates for Node.js-based microservices for the AXA DE Group, reducing the time and effort required for new service deployments. Additionally, I implemented a tracking and evaluation system for sales interfaces, providing valuable insights into their performance and usage.

Migration of a legacy e-commerce monolith into a microservice approach (full stack development)

Konsumgüter und Handel

250-500 Mitarbeiter

As a Software Engineer, I was instrumental in the development a modern bounded-context architecture for the e-commerce application, replacing the outdated monolithic system. My expertise in design and implementation ensured the creation of a highly efficient self-contained system with user-friendly APIs and a focus on scalability and clear documentation. The successful migration and decommissioning of legacy APIs was executed smoothly, ensuring a seamless transition to the new architecture.
