AI Engineer & Data Scientist

Karlsdorf-Neuthard
Niko K.

Last position:

Co-founder & AI Engineer at KAIKI GmbH

End-to-end responsibility for all products - concept, architecture, development, and production operation as the sole developer; in addition, customer meetings, proposals, and marketing.

Underwriting Copilot - AI assistant for industrial insurance (in production at customer sites)

  • Supports underwriters in analyzing industrial insurance submissions - in production use at an industrial insurer.
  • Framework-independent RAG architecture with Hybrid Search (BM25 + pgvector) across large, mixed document sets.
  • 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 at customer sites)

  • Automatically captures and analyzes menu 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.
  • Full CI/CD pipelines (GitHub Actions), production cloud deployment, interactive dashboards (Dash).

Kaiki GEO Atlas - GEO platform (in production at customer sites)

  • 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 extra LLM cost).

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 progress)

BankingGPT - AI assistant for complaint management in cooperative banking

  • Security architecture at the core: no AI draft reaches the customer without human approval - the approval decision is in auditable code, not in the language model (monotonic: the model may escalate, never downgrade).
  • Real agentic building blocks, each with its own boundary: the model chooses tools itself through an MCP server (read-only, allowlist, capped, fail-safe); sensitive cases are handed off via an open A2A protocol (JSON-RPC, Agent Card, message/send/tasks/get; client implemented by me) to a separate specialist agent (securities/law), which never lowers the review requirement (pinned by test).
  • Evaluation-driven over ten analysis rounds; uncovered a security flaw through independent review and blind tests that nine automated runs had missed.
  • Voice AI frontend, responding live: covered cases are answered in the conversation, sensitive ones escalate before generation; response latency < 7 s measured (local GPU STT/TTS).

Stack & production readiness: Python, pydantic-ai, FastAPI/Celery, PostgreSQL/pgvector, FastMCP, fasta2a, Docker; multi-tenant capable (physical vector isolation per tenant), PII encrypted, OWASP-LLM reviewed, 275 tests, CI/CD; vendor-portable (Ollama / EU Cloud Vertex).

After-Sales Assistant - agentic RAG/GraphRAG assistant on public OEM manuals (automotive after-sales)

  • Genuinely agentic on LangGraph: ReAct agent with four tools and conversation memory - the model decides on its own whether to use the manual (RAG, Chroma), a knowledge graph (GraphRAG, Neo4j/Cypher - decodes warning lights), or a workshop/booking service.
  • Human-in-the-Loop before the irreversible action: before every appointment booking, the graph pauses (interrupt) and gets the driver's explicit confirmation - the same approval-before-action discipline as in BankingGPT, in a different framework.
  • Eval as CI gate: a three-part scorecard (RAGAS grounding + deterministic tool-routing accuracy + DeepEval safety: does the answer mention the warning first when there is 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 Complaint Management Covers

Complaint Management organizes how a company receives, records, investigates and resolves customer complaints. It connects frontline service, operations, compliance and management around a traceable process. The work may also be called complaint handling, grievance management or customer complaint management, depending on the sector and internal terminology.

Core Workflows

A strong setup turns every complaint into a controlled case with clear ownership and deadlines. Experts define intake channels, categorization, priority rules, investigation steps, responses, escalations and closure criteria. They also establish how recurring issues move from individual cases into broader service improvement.

  • Design case intake and classification
  • Configure routing, ownership and escalation paths
  • Create response templates and approval flows
  • Track resolution, feedback and root causes

Systems and Tooling

Complaint processes often sit inside CRM, customer service and case management environments. Specialists work with platforms such as Salesforce Service Cloud, Microsoft Dynamics 365 Customer Service, ServiceNow and Zendesk, while integrating email, web forms, contact centres and knowledge bases. Useful adjacent skills include workflow configuration, reporting, data quality, API integration and access control.

When Companies Need Experts

Companies bring in freelance professionals when complaint volumes, fragmented tools or regulatory obligations expose gaps in ownership and reporting. External expertise is useful during a CRM rollout, service transformation, merger or process redesign. It can also help when leaders need a neutral review of unresolved cases and recurring customer pain points.

  • Replace spreadsheets and shared inboxes with controlled case handling
  • Connect complaints to customer, order and service records
  • Build dashboards for trends, backlog and resolution quality
  • Prepare teams for a new complaint operating model

What Strong Specialists Deliver

The best professionals balance customer empathy with disciplined investigation. They map the real process before configuring tools, distinguish symptoms from root causes and make ownership visible at every stage. Their deliverables may include process maps, requirements, configured workflows, escalation matrices, reporting definitions, response guidance and handover documentation.

Choosing the Right Professional

Look for evidence of complaint processes similar to yours, not only general CRM experience. Ask how the specialist handles sensitive data, disputed outcomes, vulnerable customers, multilingual communication and cross-team escalations. A practical assessment should cover case design, reporting logic, integrations and how success will be reviewed after launch.

Frequently asked questions

Everything clients usually want to know about Complaint Management, in one place.

Complaint Management is used to capture, investigate and resolve customer complaints through a consistent process. It gives teams clear ownership, records communication and helps identify recurring service, product or operational problems.

Complaint Management focuses on dissatisfaction that requires formal review, escalation or corrective action. General customer service may answer questions or complete routine requests, while complaint handling adds structured investigation, accountability and trend analysis.

Complaint Management is commonly supported by CRM and case management tools such as Salesforce Service Cloud, Microsoft Dynamics 365 Customer Service, ServiceNow and Zendesk. The surrounding setup may also include contact centre software, knowledge bases, email intake, reporting tools and API integrations.

A strong Complaint Management specialist usually understands workflow configuration, CRM data models, reporting, service design and process mapping. Experience with root-cause analysis, customer communication, information security and change adoption is also valuable.

The right Complaint Management experience depends on the scope and risk of the work. A process review may need a specialist who can map operations and define controls, while a system rollout calls for deeper configuration, integration, testing and stakeholder coordination skills.

Complaint Management projects can often be delivered remotely through workshops, documentation reviews, system configuration and online testing. On-site work may help when specialists must observe contact centre routines, facilitate sensitive stakeholder sessions or support a major operational change.

Quality Complaint Management work makes cases easy to submit, route, investigate and close without losing context. Review the clarity of ownership, escalation rules, audit trails, reporting, customer communications and the link between individual complaints and root-cause improvement.

Complaint Management is relevant wherever people can raise concerns about a service, product, decision or process. Public bodies, regulated organizations, internal service teams and business-to-business providers may all need structured grievance management with appropriate confidentiality and escalation controls.

The average hourly rate of freelancers who have used Complaint Management in their recent projects is 104 €, which corresponds to a daily rate of about 829 € based on an 8-hour working day.
