Hello visitor!

My name is Gero Hillebrandt, I live in Germany and hold an B.Sc. in Physics and an M.Sc. in Business Mathematics from the MLU Halle-Wittenberg. I am mainly interested in the various challenges of software development, ML/AI and quantitative finance. This blog is mainly for fun side projects.

swarmux: tmux-first local agent swarm orchestration

I built swarmux, a Rust CLI for local, tmux-first swarm orchestration. It gives coding agents a narrow and predictable control plane while keeping operators in direct control through tmux panes and sessions. Highlights: Submit and track tasks with deterministic states Start and monitor commands in managed tmux sessions Machine-readable JSON output for agent integrations Reconcile runtime state and prune finished resources Optional beads task tracking backend Links: GitHub: https://github.com/ghillb/swarmux Docs: http://gerohillebrandt.de/swarmux/

tmgc: Telegram MTProto Go CLI

I built tmgc, a Telegram MTProto CLI in Go. It is a thin, practical wrapper around gotd/td, focused on automation and AI agents with predictable commands and machine-friendly output. Highlights: QR login with a PNG fallback Chat history and message search Send messages (text or file) and schedule messages Human, JSON, or TSV output Session storage in the OS keychain (or file fallback) Links: GitHub: https://github.com/ghillb/tmgc Project page: https://gerohillebrandt.de/tmgc/

AI Auto Blog

Note: This experiment ran for three years and ended on 2026-01-04; all auto-generated content has been removed. TL;DR The AI Auto Blog is a fun project of mine that leverages LLM APIs and scheduled CI/CD to autonomously generate and publish daily GPT-enhanced summaries about the field of AI. Theoretically, it will keep producing content until one of the services fails or disappears. However, we may mitigate this shortcoming with the addition of a robo-maintainer in the future. ...
