Hi, I'm A. K. Holz 👋

Python developer focused on local AI and DuckDB data pipelines. I'm looking for a remote Python role as Data Engineer / AI Engineer / Python Backend.

What I'm working on

  • 🧠 Local AI: running small and quantized LLMs on my own hardware (RTX 4060 laptop for heavier models, an Orange Pi cluster for small-model/edge experiments)
  • 🦆 DuckDB + Python: turning messy real-world data into fast, queryable local databases

Featured projects

Project What it does Stack
MailData Imports mbox email data into DuckDB Python, DuckDB
HomeLabPodcastSrv Serves your audio/video folders as a podcast on your local network Python, Flask, DuckDB, Whisper
WebMap-app Web app for nmap, runs in Docker or with uv run Python, Docker
PlaylistDL Downloads lessons from YouTube and SoundCloud playlists Python, DuckDB

Tech I use

Also comfortable with: Linux (Debian/Ubuntu-based, DietPi/Armbian on ARM, Gentoo), shell scripting, home-lab networking

Currently learning
