Summary
I support companies and organizations in developing and integrating AI-powered applications. My focus is on clearly scoped solutions with Python, FastAPI, APIs, and RAG.
Possible project tasks:
- AI assistants for your own documents and knowledge bases
- Integration of LLM services into existing applications
- API connections and automation of recurring workflows
- Development and improvement of AI-powered web applications
Collaboration: I work as an independent implementation partner, not as an additional full-time resource or in shift work. We agree on the desired result, project scope, milestones, acceptance criteria, and delivery date. The work is done remotely and with self-managed working hours; we set fixed coordination meetings together.
We clarify my exact capacity before the project starts. Even within larger projects, I take on clearly defined work packages. Changes in scope as well as requirements for documentation, handover, and follow-up support are agreed on explicitly.
I bring experience with AI applications as well as B2B sales and value explaining technical decisions in a clear way. We clarify data protection requirements and the allowed use of AI tools in each project.
