Stuttgart, Germany

Profile

Engineering leader and senior platform architect with 16 years of software engineering experience, including 13 years at Mercedes-Benz. Built and scaled production cloud and API platforms from architecture through delivery and operations, providing technical leadership across internal teams and complex international, multi-vendor engineering organizations. Proven in greenfield builds as much as in highly complex grown systems: working out what is worth keeping, what has to go, and how to get to something sustainable.

Experienced in distributed systems, cloud platforms (primarily Microsoft Azure), API platforms, technical hiring and end-to-end engineering delivery, with architecture ownership and hands-on technical leadership in multi-vendor environments. From 2018 in senior expert-track positions at team-lead level.

Bringing that platform and delivery experience to AI-native software engineering: initiator and maintainer of two open-source projects, a multi-agent developer platform for persistent Claude Code, Codex and Gemini teams, and a chess engine with independently verified superhuman playing strength.

Particularly interested in engineering leadership, developer platforms and how organizations turn machine-speed implementation into sustainable product velocity.

Open-Source Projects

github.com/​taurcasa/taurhaus

taurhaus / Mesh Multi-Agent Developer Platform

Designed and built a cross-platform desktop platform for supervising persistent Claude Code, Codex and Gemini engineering teams across multiple projects.

  • Implemented persistent agent roles, cross-agent communication, task coordination, context recovery, worker-health modelling and session recovery.
  • Built an operational layer spanning local project state, Git history, tasks, search, agent processes and multi-agent coordination across Windows/WSL2 and macOS.
  • Built largely with the coding agents it manages; architecture, task decomposition and technical decisions stayed with me.
  • Practical finding: once the agents were fast enough, my own decisions and attention became the limiting resource.

Rust/Tauri, Svelte, SQLite/Tantivy, tmux

github.com/​stierms/zigqueen

ZigQueen AI-Native Chess Engine

AI-native UCI chess engine with independently verified superhuman playing strength — rated ~3570 Elo on the CCRL Blitz list.

  • Developed primarily through coding agents, with human ownership of architecture, experimentation, evaluation and release decisions.
  • Every generated change has to survive reproducible testing, benchmarking and self-play; nothing is accepted because it merely looks right.
