Commercial Offerings

Contact me if you are interested in professional services and/or project collaborations in my areas of expertise:

• Architectural coaching and architecture reviews; agile architecture practices
• Domain-Driven Design (DDD)
• Web API design and evolution
• Microservices architectures (for instance, service rightsizing)
• Cloud-native application design and cloud migrations

My profile page at OST is here (English and German).

Contributions to Open Source Projects

I lead or contribute(d) to the following projects:

• Context Mapper, DSL and tools for strategic and tactic Domain-Driven Design (DDD).
  • Three paper publications describe the concepts and provide examples.
  • (in German) “Domain-Driven Design in der Praxis - Erfahrungen mit dem Open-Source-Tool Context Mapper”
• Design Practice Repository (DPR), a collection of method elements (activities, artifacts) for service design and beyond.
  • The Y-statement artifact for architectural decision capturing is a good starting point.
• Ethical Software Engineering, combining agile practices and the value-based systems engineering processes in IEEE 7000.
• Markdown Architectural/Any Decision Records (MADR), template and lightweight tools to capture any decisions and decision rationale in Markdown.
• (no longer maintained) AD Mentor, a plugin to Sparx Enterprise Architect that supports architectural decision modeling and capturing.
• Microservice API Patterns (MAP), design patterns to identify and specify and realize services and their message APIs.
  • A short introduction can be found in a tool tip column in JavaSpektrum (in German).
• Microservice Domain-Specific Language (MDSL), a domain-specific language to specify (micro-)service contracts and their data representations (realizing the API Description pattern from MAP).
  • The MDSL Primer is a good starting point.
• Interface Refactoring Catalog, a collection of API and related architectural refactorings.
• Lakeside Mutual, a microservices sample application written in Java/Spring Boot and JavaScript (React, Vue, Angular).
• Patterns repository (work in progress): https://socadk.github.io/patterns/
• (no longer maintained) Service Cutter, originating from a bachelor thesis that I supervised.

Coaching and Mentoring

As a community activity, I can offer miscellaneous advice regarding technical writing and other topics (upon demand):

• Mentoring is one of the giveback activities of IT architects certified by The Open Group.
  • The IEEE Software Insights column that I co-edit always welcome submissions and suggestions for future columns.¹ See this post for an overview.
• Informal advice regarding thesis scoping, research and development methods, and technical writing:
  • See entries in eprints institutional repository at OST for student projects supervised.
• Opinions and pointers to existing work on all things software architecture and patterns.
