Freelance Secure AI & Solution Architect
Hattingen, Deutschland
Nur Remote
Ph.D. / Dr.-Ing. in Security & Applied Cryptography, summa cum laudeÜber mich
I help engineering, IT, and operations teams design, evaluate, and implement practical AI solutions. From automation and agentic workflows to enterprise integration, I bring architecture advice, hands-on implementation, and a security perspective.
Skills
AI AgentsRAGIntegration (Software)Cyber Threat AnalysisSolution Delivery
AI Systems & Agentic Workflows
Expertise in LLM applications, RAG, agentic systems, workflow automation, enterprise integration, and API-based AI services. Design and implementation of agentic workflows for internal and customer use cases, including company-wide knowledge bases with Open WebUI and RAG, OCR document processing workflows, and AI customer support agents.
Security Architecture & Secure AI Integration
Deep knowledge in secure AI integration, access control, agent identities and delegation, threat and data-flow analysis, privacy, and secure deployment. Experience performing systematic security and risk analyses for enterprise and automotive systems, defining architectures and controls for OEM and Tier-1 environments.
Model Evaluation & Architecture Design
Model and application evaluation, reliability analysis, model routing and selection, cost optimization, latency and quality trade-offs. Selection and evaluation of models, tools, and architectures for quality, security, latency, and cost in enterprise AI contexts.
Implementation & Prototyping
Proficiency in Python, C/C++, JavaScript/TypeScript, and Rust for building working prototypes, API integrations, cloud-native systems, and technical handovers. Rapid prototyping using coding agents and CI/CD pipelines.
AI & LLM Tooling
Hands-on experience with LangChain, LangGraph, Open WebUI, n8n, Qdrant, LangSmith, Langfuse, MLflow, LiteLLM, and OpenRouter for building and managing AI workflows and infrastructure.
Applied Cryptography & Hardware Security
Research background in formal verification and automated masking of cryptographic hardware. Development of methods and software for automated security analysis and protection of cryptographic systems, published at ACM CCS, CHES, and ASIACRYPT.
Post-Quantum Cryptography & 5G Security
Research and documentation of AI security, 5G security, and post-quantum cryptography with practical implementation guidance for enterprise environments.
Technical Writing & Architecture Documentation
Creation of architecture walkthroughs, technical articles, and reference architectures such as agentic enterprise procurement workflows with permissions, policy checks, and controlled actions, as well as technical foundations of agentic security.
