Fred Hauschel
Last position:
Software Architect and Developer at Personal project
A recurring problem in my own AI-supported projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but they remain hard to trace and scattered across Markdown files – knowledge is lost as soon as it is no longer in the context window. arknet turns requirements engineering and architecture knowledge into structured, verifiable data instead of plain text: requirements, use cases, and architecture decisions as a continuously linked knowledge graph, traceable from the requirement to the architecture decision – queryable for both people and AI agents alike. Technically based on RDF/OWL and its own MCP server.
Result: MCP daemon running, Docker image automatically published on GHCR, nine hexagonal modules, eleven ADRs (including an open-core licensing model). Requirements engineering and ubiquitous language hexagon active. Publicly available since 07/2026 as a Community Edition under Apache-2.0 (github.com/kogn-io/arknet), together with the Claude Code plugin and the GHCR image; open-core model.

About the technology
What arc42 covers
arc42 is a practical template for software architecture documentation. It helps teams describe context, goals, constraints, risks, runtime views, building blocks, and decisions in one clear structure. Companies use the arc42 template to keep architecture readable for experts, product teams, and stakeholders.
Typical use cases
- Architecture documentation for new systems and platform changes
- System overviews for reviews, handovers, and audits
- Decision records and quality goals for complex solutions
- Documentation cleanup when old docs no longer match the system
Useful ecosystem
Strong arc42 work often combines the template with UML, C4, ADRs, and diagram tools such as PlantUML or draw.io. Experts also need a good grasp of APIs, infrastructure, security, and non-functional requirements. The value is not in a long document, but in a structure that stays usable.
When freelancers help
Companies bring in arc42 specialists when architecture knowledge is spread across teams, documentation is missing, or a major change needs a clean baseline. In Munich, this often comes up in enterprise IT, mobility, finance, and software product teams that need clear technical alignment. Remote work is common; workshops on site can help when many stakeholders need one shared view.
What strong specialists do
- Turn scattered notes into a consistent architecture model
- Ask the right questions about scope, constraints, and quality targets
- Write for both technical and non-technical readers
- Keep the documentation maintainable after the project ends
Signs you need arc42 support
If architecture slides, wiki pages, and team knowledge no longer match, arc42 can bring order. It also helps when a platform grows, teams split, or a migration needs a clear description of the current and target state. A strong specialist makes the structure fit the system, not the other way around.
Frequently asked questions
The facts hiring teams ask for most often when it comes to arc42.
arc42 is used to document software architecture in a way that stays readable and useful. Teams use it to describe context, building blocks, decisions, runtime behavior, and quality goals without turning the document into a wall of text. It works well for systems that need clear alignment across product, engineering, and operations.
A strong arc42 document gives you a fixed structure, so important topics do not get skipped. A wiki page or slide deck can work for quick sharing, but it often becomes inconsistent over time. arc42 is better when you need a repeatable architecture view that others can maintain.
Bring in an arc42 specialist when your architecture knowledge is spread across people, tools, or old documents. It is also useful before a migration, a platform redesign, or a handover to a new team. In Munich, remote workshops are often enough, but on-site sessions can help when many stakeholders need to agree on one view.
A good arc42 freelancer usually brings diagramming, system design, and strong writing skills. Familiarity with APIs, cloud setups, security, and non-functional requirements helps a lot. Knowledge of ADRs, C4, and UML is often a plus because those tools fit the same documentation flow.
Yes, arc42 fits agile work well because it can grow with the system. Teams do not need to finish a huge document before they start using it. The best approach is to keep the core structure current and update the parts that change during delivery.
For a small cleanup, a generalist with solid architecture writing skills may be enough. For a complex platform, you want someone who has used arc42 on real systems and knows how to ask the right questions. The key is not just knowing the template, but knowing how to make it accurate and maintainable.
Look at whether the person can turn messy input into a clear model that your teams can keep using. A strong arc42 expert writes concise sections, spots missing decisions, and links documentation to the real system instead of assumptions. Good work is easy to update after the project ends.
Remote work is often enough for arc42 documentation, especially when system knowledge is already shared in tools and notes. On-site sessions are useful when the project needs workshops, stakeholder alignment, or a quick review of many moving parts. The best setup depends on how much shared context already exists.
