I build high-integrity software and AI-driven ecosystems, with a focus on Agentic Engineering: turning AI agents, LLMs, and autonomous workflows into reliable, secure, and production-ready systems.

As CTO of Bütema AG, I combine hands-on engineering with technical leadership across AI, retail technology, cloud architecture, and scalable product platforms.

• Agentic Systems: Designing autonomous agents, multi-agent workflows, tool integrations, memory, orchestration, and human-in-the-loop controls.
• LLM Engineering: Evaluating, fine-tuning, integrating, and operating local and cloud-based language models.
• Reliable AI: Building observable and maintainable agent workflows with clear trust boundaries, validation, and failure handling.
• AI Governance: Certified AI Officer with a focus on responsible AI adoption and the EU AI Act.
• Application Architecture: Production systems using TypeScript, NestJS, React, PostgreSQL, Swift, and Azure.

Neo is my personal OpenClaw agent. It tracks GitHub issues, monitors relevant project activity, and conducts targeted research to keep development work and technical decisions moving.

My local AI environment runs across a Mac Studio and Mac mini, combining OpenClaw workloads with local LLMs and cloud models. PickerMux connects locally hosted LM Studio models directly with my Codex Desktop workflow.

• PickerMux: Use local LM Studio models directly from the Codex Desktop model picker while keeping native Codex models available. PickerMux provides namespaced model routing, accurate context information, capability certification, and strict credential isolation.
• SourceBraid: A local-first workflow for turning web sources into durable Markdown archives that remain under the user's control.
• OpenClockwork: Self-hosted time tracking and attendance designed around real-world German working-time workflows.

At Bütema AG, I lead the technical vision for Digital Signage, Mobile ERP, AI services, and connected retail platforms.

• Mobile ERP: Real-time applications connecting store operations with enterprise merchandise systems.
• Digital Signage: CMS, device, and infrastructure platforms for global screen and LED networks.
• AI & Automation: Production AI services such as KIra, our assistant for automated retail workflows.

A UCP-native Mobile ERP architecture designed for Agentic Commerce, enabling AI agents to discover, negotiate, and purchase through structured commerce protocols.

A mobile-first ordering and operations platform for seated events, connecting guests, kitchens, runners, payments, and live revenue tracking in one real-time workflow.

If my projects save you time or help you build something better, you can support their continued development through GitHub Sponsors.

Sponsorships help cover infrastructure, testing, documentation, research, and the time required to maintain dependable open-source releases.
