Gerald Neissl NeiFlex

Gerald Neissl NeiFlex offers practical technical courses focusing on artificial intelligence, automation, and software development. The educational portfolio centers on hands-on system building, covering topics such as local artificial intelligence, Ollama, dedicated graphics processing unit servers, FastAPI, C#, and workflow automation. NeiFlex does not offer academic degree programs such as bachelor's or master's degrees, but rather specialized technical training courses aimed at system administrators, home-lab enthusiasts, and software developers. The core training currently available is Kurs 1, titled Lokaler KI-Agent mit Ubuntu, NVIDIA, Ollama & FastAPI. Delivered online through pre-recorded video clips and booked via Digistore24, this training guides learners through 31 instructional clips organized into three comprehensive modules. The curriculum takes students step by step from an empty physical machine to a fully functioning, locally hosted artificial intelligence agent operating entirely within a local area network without external internet dependencies. Module 1 focuses on hardware, setup, and the installation of Ubuntu 22.04 LTS, covering component selection, M.2 solid-state drive installation, memory configuration, graphics card assembly using an NVIDIA GTX 1080, power cabling, and initial system boot and configuration. Module 2 addresses the software foundation, including SSH remote access, NVIDIA driver and CUDA installation, directory structures, Samba network file shares, and installing Ollama to download and test language models such as Mistral, Llama 3, and IBM Granite variants. Module 3 guides learners through building the Python and FastAPI backend, handling conversation memory, extracting data from PDF, TXT, and CSV documents with libraries like pdfminer.six and PyPDF2, creating a web-based chat interface with file drag-and-drop capabilities, and configuring the entire setup as a persistent systemd background service for continuous operation.
