Niko K.
Last position:
Co-Founder & AI Engineer at KAIKI GmbH
End-to-end responsibility for all products – conception, architecture, development, and production operations as the sole developer; also customer discussions, proposals, and marketing.
Underwriting Copilot – AI assistant for industrial insurance (in production with a customer)
- Supports underwriters in analyzing industrial insurance submissions – in production at an industrial insurer.
- Framework-independent RAG architecture with Hybrid Search (BM25 + pgvector) across large, heterogeneous document collections.
- Two-stage evaluation and observability pipeline (code assertions + LLM-as-Judge) that makes answer quality, retrieval accuracy, and citation integrity measurable in a regression-safe way.
Kaiki Menu Analyzer – Data intelligence platform (in production with a customer)
- Automatically collects and analyzes food data from around 25,000 German restaurants.
- Scalable 7-container architecture (FastAPI, partitioned PostgreSQL, Redis/RQ) with LLM-supported extraction of structured data from PDF, HTML, and images.
- Complete CI/CD pipelines (GitHub Actions), production cloud deployment, interactive dashboards (Dash).
Kaiki GEO Atlas – GEO platform (in production with a customer)
- Measures brand visibility across five AI engines (ChatGPT, Gemini, Perplexity, Grok, Claude), each augmented with web search, orchestrated as a DAG workflow pipeline (Dispatcher → Sub-Workflows → Scoring → Report) with fail isolation.
- 6-container deployment (FastAPI, Celery, Redis, PostgreSQL); LLM cost estimation, PDF audit report, rule-based cross-signal insights (no additional LLM effort).
Data Pipeline & Analytics Platform – Competitive analysis in the automotive aftermarket
- Automated data pipeline with gap analysis algorithms and role-based access control; 230+ tests.
- Backend with FastAPI, PostgreSQL, SQLAlchemy.
Product development (actively in development)
BankingGPT – AI assistant for complaint management in cooperative banking
- Security architecture at its core: no AI draft reaches the customer without human approval – the approval decision is stored in auditable code, not in the language model (monotonic: the model may increase the level, but never lower it).
- Genuine agentic components, each with its own boundaries: the model selects tools itself through an MCP server (read-only, allowlisted, capped, fail-safe); sensitive cases are sent via the open A2A protocol (JSON-RPC, Agent Card, message/send/tasks/get; client implemented independently) to a standalone specialist agent (securities/law), which never lowers the review requirement (pinned by tests).
- Evaluation-driven across ten analysis rounds; an independent review and blind tests uncovered a security defect that nine automated runs had missed.
- Voice AI frontend, responding live: covered cases are answered during the conversation, while sensitive cases are escalated before generation; measured response latency < 7 s (local GPU STT/TTS).
Stack & production readiness: Python, pydantic-ai, FastAPI/Celery, PostgreSQL/pgvector, FastMCP, fasta2a, Docker; multi-tenant (physical vector isolation per tenant), encrypted PII, OWASP-LLM-reviewed, 275 tests, CI/CD; provider-portable (Ollama / EU-Cloud-Vertex).
After-Sales Assistant – agentic RAG/GraphRAG assistant based on public OEM manuals (automotive after-sales)
- Genuinely agentic with LangGraph: ReAct agent with four tools and conversation memory – the model decides itself whether to use the manual (RAG, Chroma), a knowledge graph (GraphRAG, Neo4j/Cypher – decoding warning lights), or a workshop/booking service.
- Human-in-the-loop before the irreversible action: before every appointment booking, the graph pauses (interrupt) and obtains the driver's explicit confirmation – the same approval-before-action discipline as in BankingGPT, in a different framework.
- Eval as a CI gate: three-part scorecard (RAGAS grounding + deterministic tool-routing accuracy + DeepEval safety: does the answer mention the warning first in the case of a critical warning?) blocks the pipeline; provider-agnostic (OpenAI/Azure/Anthropic), FastAPI with token streaming.
Stack: Python, LangChain/LangGraph, Chroma, Neo4j, RAGAS/DeepEval, FastAPI, Docker.

About the technology
What Grok does
Grok is a generative AI system from xAI for conversational interaction, reasoning, content generation and question answering. Teams use it through consumer experiences, the Grok API and integrations connected to business applications. Its access to current information can support research, assistance and operational workflows, when configured with suitable controls.
Product use cases
Grok can support products that need natural language input, grounded answers or automated actions. Common deliverables include:
- Customer and employee assistants with conversation history
- Research tools that summarize and compare current information
- Content workflows for drafting, classification and transformation
- Internal search using retrieval-augmented generation
- Agents that call approved tools and business services
Ecosystem and tooling
Work with the Grok API, model endpoints, authentication, structured outputs and tool-calling patterns. Strong specialists also understand prompt design, context management, retrieval pipelines, vector stores, evaluation sets and guardrails. Integrations may involve Python or TypeScript services, REST interfaces, web applications, data platforms and observability tools.
When companies need expertise
Companies often bring in freelance specialists when an experiment must become a dependable product feature, or when an existing assistant produces inconsistent answers. The need may involve selecting a model, preparing source data, connecting enterprise systems or establishing review and monitoring processes. In Germany, collaboration may also need clear coordination between local product teams and remote specialists.
What strong specialists deliver
A capable Grok professional turns a vague AI idea into a testable workflow with defined inputs, outputs and escalation paths. They protect confidential data, separate retrieved facts from generated text and design prompts that remain stable as requirements change. They can explain trade-offs around latency, context limits, tool permissions and answer quality in terms that stakeholders can use.
Evaluating project fit
Look for evidence of shipped conversational systems, API integrations and practical evaluation methods rather than prompt examples alone. Ask how the specialist handles hallucinations, sensitive information, failed tool calls and changing source content. German-speaking teams may also value fluent German communication, while remote work can succeed when access, documentation, handovers and decision rights are agreed early.
Frequently asked questions
Questions about Grok? Start with the answers below.
Companies use Grok for conversational assistants, research support, content operations, internal search and workflows that combine language understanding with tool calls. Through the Grok API, a specialist can connect these capabilities to approved data sources and business systems.
Grok is often evaluated alongside models from OpenAI, Anthropic and Google. The right choice depends on response quality, current-information access, context handling, tool support, data requirements, integration effort and operational controls rather than on a single model label.
A strong Grok expert usually combines API integration with prompt design, retrieval-augmented generation, structured outputs and evaluation. Experience with Python or TypeScript, REST services, vector search, cloud security and observability is useful for production work.
A small proof of concept can be handled by one Grok specialist who understands the API and the target workflow. Production use normally requires broader experience with data protection, testing, access controls, failure handling and monitoring, especially when the system can trigger business actions.
Yes. Grok work is commonly suitable for remote collaboration because the main activities involve APIs, software repositories, data design and shared evaluation. German companies should define access permissions, documentation standards, meeting language and handover rules before work begins.
Use the Grok API when the capability must run inside a product, service or repeatable internal workflow. A chat interface may be enough for individual research, but an API integration allows controlled inputs, application logic, tool permissions, logging and consistent user experiences.
Ask a Grok specialist to explain a comparable system from data preparation through evaluation and production monitoring. Good answers address grounding, prompt changes, unsafe or incorrect outputs, tool failures, privacy boundaries and measurable acceptance criteria without relying only on impressive demonstrations.
Working with Grok requires keeping up with xAI model and API behavior, authentication, request handling and available tool features. Professionals should also clarify data access, expected response formats, evaluation examples, deployment ownership and how the client will review model changes over time.
