Co-developer at Nikan AI Solutions GmbH
Multi-Agent Document-Generation Platform
Problem:
Turn a single prompt into a well-researched, structured and cited document, while keeping the user in control: every stage can be reviewed, corrected or revisited before the system moves on.
Architecture:
A multi-agent system orchestrated by a central controller. More than 20 specialised pydantic-ai subagents (understanding, structuring, planning, research, writing, assembly, cross-reference check, glossary, citation, reference table and more) pass results forward through a shared plan persisted in Postgres (asyncpg); a runner layer dispatches each task by name to its agent, and mechanical steps such as formatting, table of contents and list of figures are deterministic code instead of LLM calls. Provider (Anthropic or OpenAI) is a configuration setting, and responses stream over Server-Sent Events.
Hosting & Infrastructure:
Stateless container run as a Scaleway Serverless Container on a private network with managed PostgreSQL, object storage for finished documents and assets, and centralized log shipping (Loki / Scaleway Cockpit), provisioned with OpenTofu modules and deployed through GitLab CI; usage is metered per API key.
My Contribution & Key Decisions:
- Central decision controller: a satisfaction classifier turns the user's free-text feedback into a verdict (keep working, advance, cancel or revise an earlier task), and a middleware applies it to the plan. Plan progression supports jumping back to earlier tasks and re-running the stages after them.
- Research and writing fan-out: planning produces a plan from which a research-design agent generates individual research tasks and a writing-design agent generates individual writing tasks, each linked to the research it needs. Every task runs in its own dedicated agent with its own conversation history.
- Self-review and human-in-the-loop: after each step a critical-thinking agent reviews the output; the user can accept, refine, or ask questions about a critique before the plan advances.
- MCP integrations: two remote MCP servers, web search and internal document search, connected through pydantic-ai with retries and long-running tool-call timeouts. Classifier agents decide per task whether web search is needed, and a small model condenses raw search results into structured findings before they reach the writing agents.
Usage Metering:
Clients authenticate with an API key validated against a key-management service; consumption is charged in credits calculated from token usage per model plus a markup, and exhausted quota is answered with HTTP 429.

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
Reproducible documents
R Markdown combines narrative text, executable R code and rendered output in one source document. Specialists use it to create analysis reports, research papers, technical documentation and presentations that can be regenerated when data or assumptions change. The workflow keeps explanations, calculations and results connected.
Formats and outputs
A single R Markdown source can produce HTML pages, PDF reports, Word documents, slides and dashboards. Output depends on the document format, templates, styling rules and publishing target. Strong professionals select the right format for the audience and make sure charts, tables, references and navigation remain consistent after rendering.
R ecosystem
R Markdown work commonly includes R, knitr, tidyverse packages and the RStudio or Posit environment. Specialists may also use Shiny for interactive applications, Quarto for newer publishing workflows, Git for version control and package managers for dependable environments. Familiarity with Markdown, YAML, CSS, LaTeX and SQL is often valuable.
Typical projects
- Automate recurring management or regulatory reports
- Build analytical notebooks for data exploration
- Publish research, clinical or educational materials
- Create parameterized documents for different audiences
- Connect reports to databases and scheduled data pipelines
The right approach depends on data sensitivity, review needs, output formats and how often content must be refreshed. Professionals can also prepare reusable templates and publishing processes for internal teams.
When to bring in specialists
Companies often seek freelance expertise when reports are manually assembled, results are difficult to reproduce or a team needs to move from exploratory analysis to a governed reporting process. A specialist can refactor existing R scripts, resolve rendering problems, improve document structure and connect R Markdown to data sources or delivery workflows. In Germany, remote collaboration is common, while on-site work can help with stakeholder workshops and internal handover. German or English communication should match the project team.
What quality looks like
A strong professional separates data preparation, analysis and presentation without breaking reproducibility. They use clear project structure, stable package environments, meaningful error handling and source control. They test rendered outputs across the required formats and make accessibility, security and reviewability part of the delivery. Good documentation lets another person run, inspect and maintain the work rather than treating the report as a one-off file.
Frequently asked questions
The facts hiring teams ask for most often when it comes to R Markdown.
R Markdown is used to combine written explanation, R code and generated results in a single document. Companies use it for recurring reports, research outputs, analytical notebooks, presentations and data-driven documentation.
R Markdown has a mature ecosystem around knitr, RStudio or Posit, and many existing templates and projects. Quarto offers a newer publishing approach with broader language support, so the right choice depends on compatibility needs, team skills and whether an existing workflow must be maintained.
A capable R Markdown specialist often works with tidyverse packages, knitr, Git and database queries. Depending on the deliverable, useful adjacent skills include Shiny, SQL, YAML, CSS, LaTeX, testing and automated publishing.
The scope of R Markdown work matters more than a generic experience label. A simple report may need strong R and document-format skills, while a governed reporting pipeline calls for reproducibility practices, version control, data integration, testing and deployment knowledge.
R Markdown projects are often well suited to remote collaboration because source files, data connections and rendered outputs can be reviewed digitally. Clear access rules, documented environments and agreed review steps are important, especially when teams in Germany work across locations or languages.
R Markdown can include interactive charts, widgets and embedded outputs, and it can work alongside Shiny for richer applications. A specialist should clarify whether the goal is an interactive report, a parameterized document or a full application before choosing the implementation.
A strong R Markdown deliverable should render reliably, explain its assumptions and reproduce its results from a clean environment. Review the source structure, dependency management, output tests, accessibility, documentation and how easily another professional can update the document.
R Markdown rendering issues often come from missing packages, inconsistent environments, invalid YAML, unavailable data, path assumptions or format-specific styling. An experienced specialist isolates dependencies, uses stable project paths, records setup instructions and tests the final output rather than checking only the source file.
The average hourly rate of freelancers in Germany who have used R Markdown in their recent projects is 92 €, which corresponds to a daily rate of about 737 € based on an 8-hour working day.
