Portrait of Denis Knaack

Denis Knaack

Software engineering in the age of AI.

I help companies assess AI realistically and use it where it adds value – from business case and requirements through architecture and software engineering to production operations. When needed, I also take responsibility for implementation – independently or together with existing teams.

25 years of professional software engineering. In recent years, my focus has been on AI systems, agentic architectures, and the dependable integration of modern models.

Current insights

Technical capabilities, product marketing, and actual risks are often mixed together in AI discussions. I write about models, architectures, data protection, costs, and lessons from practical implementation.

  1. AI costs Token pricing

    Why intensive users can receive remarkable value from an AI subscription—and why exceptionally cheap offers still deserve closer scrutiny.

  2. GDPR CLOUD Act

    Why a European server location is not enough—and why the provider’s jurisdiction, the server location, and the route to the model must be assessed together.

How I support companies and teams

Good AI systems begin with a realistic assessment of the problem. Model selection, architecture, and implementation follow from there.

  • Assess AI initiatives realistically

    Not every interesting use case is economically or technically viable. I help assess value, data, risks, costs, and the conditions required for dependable operation.

  • Architecture and technical decisions

    Model selection, hosting, data protection, and integration cannot be considered independently. I design architectures that fit the use case and the existing system landscape.

  • Build production-grade software

    I turn ideas, requirements, and business cases into maintainable software systems, including backends, interfaces, AI components, user interfaces, tests, deployment, and operations.

  • Improve existing systems

    Many AI systems are unnecessarily slow, expensive, or difficult to reproduce. A clearer separation between deterministic processes and tasks that genuinely need a model often helps.

This selection shows how I combine architecture, established software engineering, and modern AI components into production-grade systems.

From idea to production system

Modern software engineering connects business requirements, technical decisions, and operations whose quality remains verifiable.

Experience, technical depth, and a clear view of what is viable

Twenty-five years of professional software engineering form the foundation of my work. Today, I combine that experience with hands-on AI expertise, software architecture, and the ability to turn requirements into production-grade systems.

Collaboration

A demanding AI or software initiative?

I support assessment, requirements, architecture, implementation, and optimization – as a clearly scoped project, technical consulting engagement, or long-term collaboration.
