Andreas Sawall

I build AI and automation solutions that run in daily operations, not just in prototypes. Focus: Workflow automation with n8n, RAG and LLM applications (OpenAI, Anthropic Claude) and the right infrastructure for it, self-hosted and GDPR-compliant.

What distinguishes me from pure developers: 25 years of B2B sales and management. I understand not only the code, but also the business behind it. Before I automate, I look at where you are really losing time and money, and then I focus on that. My roots are in industrial automation (PLC, EtherCAT), today I develop full-stack: .NET 8, NestJS, Next.js, FastAPI, PostgreSQL, all in Docker.

Typical projects:

- Automate recurring processes (quotes, invoices, onboarding, data synchronization) with n8n and API integrations

- AI assistants and RAG systems on your own data, without company internal data migrating to external clouds

- SaaS and backend systems from architecture to productive operation

- Connect existing tools cleanly, instead of buying another island solution

If you are planning an automation or an AI feature and are looking for someone who will finish it and also put it into operation, contact me. You can get an initial assessment quickly and easily.
