Fred H.
Last position:
Software Architect and Developer at Personal project
Recurring problem in my own AI-assisted projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but remain difficult to follow 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 form a consistently linked knowledge graph, traceable from requirement to architecture decision – queryable by both people and AI agents. Technically based on RDF/OWL and a custom MCP server.
Result: Working MCP daemon, Docker image published automatically to GHCR, nine hexagonal modules, eleven ADRs (including an Open-Core licensing model). Requirements engineering and Ubiquitous Language hexagons are active. Public as a Community Edition under Apache-2.0 since 07/2026 (github.com/kogn-io/arknet), together with the Claude Code plugin and GHCR image; Open-Core model.

About the technology
Architecture Documentation
arc42 is a practical template for documenting software architecture. It gives teams a consistent structure for recording goals, constraints, context, building blocks, runtime behavior, deployment and key decisions. The format is technology-neutral and works alongside agile delivery.
What It Builds
arc42 does not build software itself. It helps teams make complex systems understandable and maintainable by connecting architecture decisions with implementation and operations.
- Document system context and external interfaces
- Describe containers, components and responsibilities
- Explain runtime scenarios and deployment views
- Record risks, technical debt and architecture decisions
Template And Tools
The arc42 template can be maintained in Markdown, AsciiDoc, wikis or documentation portals. Strong specialists adapt the structure to the team rather than treating it as a fixed form. They often connect it with Git, architecture decision records, diagrams using PlantUML or Mermaid, and automated documentation workflows.
When Expertise Helps
Companies bring in freelance arc42 expertise when documentation is missing, outdated or difficult for non-specialists to use. This is common during platform modernisation, system separation, cloud migration, acquisitions and audits. In Munich, specialists may support local product teams on site while coordinating documentation work remotely with distributed stakeholders.
- Establish a usable documentation structure
- Recover architecture knowledge from an existing system
- Facilitate decisions across business and technical groups
- Align documentation with delivery and operations
Adjacent Skills
arc42 work depends on more than filling in headings. Professionals need to understand software architecture, domain boundaries, APIs, integration patterns, security concerns and deployment environments. Clear writing, diagramming and workshop facilitation are equally important when several teams must agree on one architectural view.
Quality Signals
A strong arc42 document answers real questions without hiding uncertainty behind vague language. It names assumptions, explains trade-offs, links decisions to consequences and stays close to the running system. Good specialists establish ownership and review habits so the documentation remains useful after the initial engagement.
A company selecting a freelancer should examine representative architecture documentation, their approach to confidential system information and their ability to work with existing tools. For teams in Munich, German or English collaboration can be agreed around stakeholders, workshops and the documentation itself.
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 structured, technology-neutral way. It helps teams explain system context, technical decisions, building blocks, runtime behavior, deployment and quality requirements.
arc42 is a documentation structure, while UML and C4 are modelling or diagramming approaches. Teams can use UML or C4 diagrams inside an arc42 document, combining a clear narrative with visual views of the system.
An arc42 specialist should understand software architecture, domain modelling, APIs, integration, security and deployment environments. Facilitation, technical writing, Git-based documentation and tools such as PlantUML or Mermaid are also valuable.
An arc42 engagement needs enough system understanding to document real decisions rather than produce generic text. The depth required depends on system complexity, available source material, stakeholder access and whether the work covers discovery, review or ongoing maintenance.
arc42 documentation works well in remote collaboration when diagrams, decisions and review comments are kept in shared, versioned tools. Workshops may still benefit from on-site sessions, especially when domain knowledge is spread across teams in Munich and elsewhere.
arc42 can be maintained in Markdown, AsciiDoc, wikis and documentation portals. A specialist may connect it with Git, PlantUML, Mermaid, architecture decision records and automated publishing so the content fits the existing engineering workflow.
High-quality arc42 documentation is specific, navigable and honest about risks, assumptions and trade-offs. Ask for a redacted sample, check whether decisions can be traced to consequences, and assess how the specialist plans reviews and ownership.
arc42 is well suited to legacy systems because it can capture the current architecture before changes begin. It also provides a useful structure for documenting target states, migration steps, constraints and decisions during modernisation or system separation.
