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 companies receive, classify, investigate and resolve customer complaints. It connects customer communication with cases, owners, deadlines, evidence and outcomes. The discipline supports consistent service recovery while giving teams a clear record of recurring problems.

Processes and outcomes

Professionals turn informal messages into controlled workflows that move from intake to closure. They define categories, priorities, ownership rules, escalation paths and response templates. Good processes help companies protect customer relationships and convert complaint data into operational improvements.

  • Capture complaints from email, web forms, phone and social channels
  • Route cases to the right team and specialist
  • Track investigations, actions, approvals and resolutions
  • Identify recurring causes and service gaps

Systems and tooling

Complaint Management often sits inside CRM, customer service and case management environments. Work may involve Salesforce Service Cloud, Microsoft Dynamics 365, Zendesk, ServiceNow or custom applications. Strong specialists understand integrations, identity and access, workflow configuration, reporting, data quality and secure handling of customer records.

When companies need support

Companies bring in freelance expertise during CRM rollouts, service transformation, acquisitions or periods of rising complaint volume. They may need a process review, a configured case model, data migration, reporting or integration with contact-centre tools. External support is also useful when internal teams need an independent view of bottlenecks and control gaps.

  • Complaint workflows differ across teams or regions
  • Cases are lost between email, phone and service channels
  • Escalations depend on manual reminders
  • Managers lack reliable root-cause and resolution reporting

Skills that matter

A capable professional combines customer service process design with practical system knowledge. They can map journeys, define service rules, configure forms and queues, and explain trade-offs to business and technical stakeholders. Useful adjacent skills include CRM administration, API integration, data analysis, knowledge management, quality assurance and change enablement.

How to judge quality

Look for evidence of complete complaint workflows, not only system configuration. Strong work shows clear ownership, usable forms, meaningful categories, auditability and reports that support action. Ask how the specialist handles sensitive information, complex escalations, multilingual teams and changes after launch. A short discovery exercise can reveal whether they understand both customer impact and operational detail.

Frequently asked questions

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

Complaint Management is used to capture, route, investigate and resolve customer complaints in a consistent way. It helps teams track ownership, communication, escalation and corrective action from the first contact through closure.

Complaint Management adds specialized workflows to a broader CRM system. A CRM may store customer interactions, while complaint handling focuses on case classification, investigation, service commitments, escalation, audit trails and root-cause analysis.

A strong Complaint Management specialist may also bring CRM configuration, API integration, data migration and reporting skills. Knowledge of customer service operations, knowledge bases, contact-centre processes and change enablement is valuable for adoption.

The required experience depends on the scope and risk of the work. A simple workflow adjustment may suit a configuration specialist, while a company-wide rollout needs someone who can map processes, govern data, manage integrations and coordinate stakeholders.

Yes, much of Complaint Management work can be completed remotely through workshops, system access and shared documentation. On-site sessions can still help with contact-centre observation, process discovery, training or stakeholder alignment, especially across teams in Germany or other local markets.

A company may need dedicated Complaint Management software when complaints require complex regulatory controls, independent case governance or specialized investigation workflows. CRM functionality can be sufficient when the process is simpler and customer records, service cases and reporting already sit in one environment.

A Complaint Management professional may deliver process maps, case categories, routing rules, escalation models, forms, integrations, dashboards and test scenarios. They should also document decisions, permissions, data definitions and the operating process after launch.

Ask for examples showing how the specialist improved intake, ownership, resolution visibility and root-cause reporting. A high-quality Complaint Management professional can explain their design choices, protect sensitive customer data and demonstrate how users will work with the process in daily operations.

The average hourly rate of freelancers who have used Complaint Management in their recent projects is 105 €, which corresponds to a daily rate of about 842 € based on an 8-hour working day.
