Sara Schönherr
Last position:
Senior Software Developer with a Focus on UI/UX at vGen GmbH
Development of an interactive prototype for the concept of an AI-supported Enterprise Architecture Management tool. The goal was to present complex relationships between IT systems, business processes, and departments in a way that is easy to understand and to support decision-making in the context of IT transformations.
The prototype combined data-driven analyses with guided questions and interactive visualizations. A central part was the integration of a RAG process to provide domain-specific EAM knowledge in context. The focus was on quick idea validation, user-centered interaction design, and the technical feasibility of a scalable overall concept.
Design, implementation, and validation of a RAG process for domain-specific EAM knowledge with Python, LangChain, and graph/vector databases (Neo4J, Milvus)
Business and technical requirements analysis as well as definition of an MVP
Development of the architecture and technology concept using Angular, Spring Boot, GraphQL, and Kubernetes

About the technology
What RAG does
Retrieval-Augmented Generation, often called RAG, combines search with text generation. It lets systems pull relevant facts from internal documents, databases, or knowledge bases before they answer. That makes responses more grounded than a model working from its own memory alone.
Common use cases
- Internal knowledge assistants for support, sales, and operations
- Document question answering over manuals, policies, and contracts
- Search-driven chat for product content, case notes, or research
- Answer generation with citations and source snippets
Core stack
Strong professionals working with RAG know the full path from data to answer. They work with embeddings, chunking strategies, vector databases, rerankers, prompt design, and evaluation workflows. They also understand how retrieval quality affects the final response.
When to bring in specialists
Companies usually bring in freelance expertise when a prototype has to become dependable. Common signs are weak answer relevance, hallucinated details, slow retrieval, poor source coverage, or messy document pipelines. Dusseldorf teams often use specialists for local rollout, while the system itself can be built and reviewed remotely.
What strong specialists deliver
Good RAG professionals do more than connect a model to a search index. They test retrieval paths, improve grounding, reduce duplicate results, and set up checks for answer quality. They can also adapt the system for multilingual content, domain jargon, and strict source requirements.
Adjacent skills
- Python, API design, and application integration
- Vector databases and semantic search
- LLM prompt design and structured outputs
- Document processing and data cleaning
- Evaluation, observability, and guardrails
Frequently asked questions
What clients ask us most about Retrieval-Augmented Generation — answered in short.
Retrieval-Augmented Generation is used to answer questions from company knowledge that lives in documents, tickets, portals, or databases. It is common for support assistants, policy search, product guidance, and research tools where answers must be tied to current sources. The goal is to combine retrieval with generation so the response is both useful and grounded.
RAG is usually the better choice when the knowledge changes often or must come from specific sources. A plain chatbot can sound fluent but miss the facts, while fine-tuning changes model behavior without giving it a live knowledge base. RAG keeps the model tied to retrieval, which makes source control and updates easier.
A strong Retrieval-Augmented Generation specialist usually knows Python, embeddings, chunking, vector search, prompt design, and evaluation. Experience with document parsing, reranking, and API integration helps a lot too. For enterprise work, the person should also understand access control, source traceability, and multilingual content.
A RAG project can start with a focused prototype, but production work needs more depth. The person should have shipped retrieval pipelines, handled noisy data, and improved answer quality with real feedback loops. If the scope includes multiple data sources or strict accuracy requirements, you want someone who has solved those problems before.
Yes, Retrieval-Augmented Generation work is often remote-friendly because most tasks live in code, data, and evaluation. Dusseldorf teams may still want on-site workshops for source selection, security review, or stakeholder alignment. The best setup is often a mix of remote implementation and a few focused working sessions.
The main alternatives to Retrieval-Augmented Generation are traditional keyword search, rules-based knowledge bases, and fine-tuned model setups. Keyword search is strong for exact terms, but it does not generate answers well. RAG is usually preferred when people need natural language answers with clear source grounding.
Look for proof that RAG answers are accurate, traceable, and stable across real documents. Good specialists can explain their retrieval strategy, show evaluation results, and describe how they handle bad chunks, duplicate hits, and weak sources. If they can talk clearly about failure modes, that is a strong sign.
Before bringing in Retrieval-Augmented Generation expertise, prepare a clear use case, sample documents, access rules, and a definition of what a good answer looks like. It also helps to list the systems that need to connect, such as search, storage, and authentication. In Dusseldorf, that preparation makes both remote and on-site collaboration much smoother.
