Senior Java Architect and Developer | Domain Architect (DDD, Knowledge Systems)

Last position:

Software Architect and Developer at Personal project

Recurring problem in my own AI-assisted projects: requirements analysis, use cases, and architecture decisions are created quickly with AI support, but they remain hard to trace and are 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 fully linked knowledge graph, traceable from the requirement to the architecture decision – queryable for both people and AI agents. Technically built on RDF/OWL and its own MCP server.
Result: MCP daemon running, Docker image automatically published to GHCR, nine hexagonal modules, eleven ADRs (including an open-core license model). Requirements engineering and ubiquitous language hexagon active. Public 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.
Label: Java, Maven, RDF, RDF4J, OWL, SPARQL, Model Context Protocol, Spring AI, Docker, GitHub, Git, Claude Code, Obsidian, DDD, Hexagonal Architecture, ArchUnit, JUnit, AssertJ
