Summary

As a freelance software architect and Principal AI Engineer with over 20 years of experience, I help companies optimize product and architecture decisions in tandem – from strategy and roadmap to technical governance and production-ready implementation. My focus is on robust, transparent, and reliable systems, as well as innovative AI applications.

Architecture & product ownership: End-to-end control of vision, roadmap, backlog, and releases with clear decision governance and transparent architecture standards.
AI/LLM systems: Designing and implementing LLM-based components (RAG pipelines, agent-based workflows, LangChain/crewAI, PyTorch) with an emphasis on robustness, evaluation, reproducibility, and operational stability.
Platform and integration architectures: API and microservice design, event-driven integration, security-by-design (OWASP, BSI), and hybrid cloud/on-premise solutions.
Team and stakeholder leadership: Leading requirements analysis, prioritization, and delivery in cross-functional teams of up to 20 people; coordinating across multiple stakeholders and dependencies.
Cloud & DevOps: Establishing cloud-native delivery with Kubernetes, CI/CD, and infrastructure as code in AWS, Azure, and GCP.
Industries: Banking, insurance, energy, telecommunications, industry, tourism, media companies, public sector, e-commerce.

Currently, I am developing scientifically grounded AI tools for macroeconomic analysis and company valuation with my own platform Macropulze (macropulze.com) – including published models and public live demos.
