Dear Priya Santhosh,

Thank you for your Freelancermap message. I am very glad to apply as AI Expert for Sales and Services, because the project matches my current focus on AI agents, RAG and self-hosted AI infrastructure precisely.

**Availability:** I am available from 1 September 2026 full time.

**Hourly rate:** My all-in hourly rate expectation is 93 € net.

**Remote:** I deliver the work fully remote in dedicated office rooms with professional IT equipment.

Since March 2026 I have been working intensively with Claude, including software design with Claude Code, which I use productively in my own business. To keep this work structured I rely on the Superpowers extension most of the time, and I develop my own agent skills, for example one that retrieves project descriptions from portals, evaluates them against my competence profile and writes the result into my CRM through its REST API. This is very close to the skill based approach with defined routes that your agentic framework is moving towards.

Building reusable AI agents, equipping them with tooling and connecting them to data sources belongs to my experience, as does the operation of the resulting components. For RAG and vector search I have created the chunks, generated the vectors with embedding models and loaded them into a vector database, and I have validated the quality of the semantic search. Local LLM inference runs on my own local AI server with Linux and Blackwell GPU, where Qwen models are among those I have evaluated and operated. The documents I process this way are largely in German.

Deciding which cloud services to use and which services to host myself is a regular decision in my own environment. Self hosted services run either on my own GPU server or on one of my Hetzner servers, in both cases as containerized services with Podman or Docker, which lets me weigh cost, scalability and data protection case by case. I have operated my own Linux root servers since 2011, including reverse proxy, TLS, backups and monitoring, so deploying front end artifacts such as dashboards behind a secured connection and isolated from the rest of the system is familiar ground. Linux, including embedded Linux, has accompanied me for decades, and VS Code and VS Codium are my everyday development environments.

In several positions I have accompanied complex technical systems from the ground up, from gathering the requirements through solution concepts and implementation to verification, deployment and an orderly handover. Knowledge transfer is lived practice for me: in all my projects I have passed my knowledge on to my customers' teams continuously, in regular update meetings, in direct exchange with the experts as needed and through careful documentation. Reducing the key person dependency of your project is therefore a goal I share.

Attached please find my current CV and my TÜV certificate as an AI Consultant. I would be delighted about your interest and remain at your disposal for any questions or a conversation at any time.

Best regards,

   Thomas Langer
