Agentic Automation and a RAG system
- This project involved extraction of intelligence data to support report writing for a company that provides geopolitical, global, commercial intelligence. The data have been gathered from a number of resources (interview transcripts, online data, internal documents), and then a knowledge base has been build from it. This was the basis of a complex RAG system, that was evaluated against a golden dataset. Agents have been used to find out the contradicting intelligence, the statements supporting each other, and to store back the generated knowledge.
Used: Python, RAG, LangGraph, LangChain, deepeval, MCP

About the technology
What LangChain does
LangChain is an open-source framework for building applications around large language models. It connects models to prompts, documents, databases, APIs and business tools so an application can do more than generate isolated text. Teams use it for chat assistants, search interfaces, document workflows and task automation.
Core application patterns
LangChain supports composable chains, tool-calling workflows and agent systems that select actions at runtime. Strong implementations combine model calls with clear state handling, structured outputs, retries and human approval where needed. Retrieval-augmented generation is a common pattern for grounding answers in company knowledge.
- Conversational assistants with memory and session context
- Document search and question answering with RAG
- Tool-using agents for business processes
- Structured extraction from contracts, tickets and reports
Ecosystem and tooling
The framework works with model providers such as OpenAI, Anthropic and Google, as well as embedding services and vector stores. LangSmith helps teams trace, test and evaluate runs, while LangGraph is suited to stateful, multi-step agent workflows. Professionals also bring experience with Python or JavaScript, REST APIs, SQL, Docker and cloud deployment.
When companies need specialists
Companies often bring in freelance LangChain expertise when a prototype must become a dependable product, or when internal teams need to connect models to sensitive data and existing systems. Specialists can select the right retrieval design, define prompt and tool boundaries, and expose an application through an API or user interface. In Munich, this can support local product, manufacturing, finance and research teams while allowing remote collaboration across locations.
- A proof of concept needs production architecture
- Model responses require evaluation and observability
- Private documents must be retrieved with access controls
- Agents need safeguards, fallbacks and approval steps
What strong professionals deliver
Experienced professionals treat LangChain as application infrastructure, not as a substitute for sound engineering. They separate prompts, business rules and provider integrations, keep workflows testable, and measure groundedness, relevance, latency and cost without relying on impressive demos. They also understand data protection, secrets management, authentication and failure handling.
Choosing the right fit
Review comparable systems rather than generic model experience. Ask how the specialist would trace a chain, prevent unsupported answers, handle changing model behavior and evaluate retrieval quality on your data. A good engagement starts with a small, testable workflow and clear acceptance criteria, then expands only after the system performs reliably in real operating conditions.
Frequently asked questions
Everything clients usually want to know about LangChain, in one place.
LangChain is used to build applications that combine language models with prompts, external data, APIs and business tools. Typical projects include retrieval-augmented chat, document extraction, workflow automation and agents that decide which tool to use.
LangChain provides reusable components for model calls, retrieval, tools and agents. LangGraph focuses more directly on stateful, multi-step workflows with explicit transitions, which can make complex agent behavior easier to control and inspect.
LangChain becomes useful when an application needs several integrations, retrieval steps, tool calls, memory or structured orchestration. A direct model API may be simpler for a narrow prompt service with little surrounding logic.
A strong LangChain specialist usually understands Python or JavaScript, REST APIs, databases, embeddings and vector search. Experience with cloud deployment, evaluation, observability, authentication and data protection is also valuable.
The right level depends on the system, not on the framework alone. A simple prototype may need prompt and integration skills, while a production application benefits from someone who has handled retrieval quality, model failures, access control, testing and operational monitoring.
Yes. LangChain projects can usually be delivered remotely through shared repositories, documented interfaces, cloud environments and regular technical reviews. For Munich-based teams, occasional on-site workshops can help clarify domain data, security requirements and approval processes.
Ask for a clear explanation of the proposed workflow, data flow and failure modes. A capable LangChain professional should demonstrate tracing, evaluation, grounded responses, secure tool access and a practical plan for testing changes to prompts or models.
A freelancer should clarify the target users, source data, model constraints, expected integrations and definition of a correct answer. With LangChain, it is especially important to agree on retrieval permissions, evaluation examples, human review points and how production behavior will be monitored.
The average hourly rate of freelancers in Munich, Germany who have used LangChain in their recent projects is 96 €, which corresponds to a daily rate of about 765 € based on an 8-hour working day.
