Head of Product by day. Builder of things by night.
I lead product at filu in Munich. Before that, I built product at Personio, co-founded a disc golf app that organically grew to 1,500 users in six weeks, and helped launch corporate ventures at Deloitte Digital.
When I'm not doing product work, I write code — mostly to scratch my own itch.
Tools and plugins for working with AI coding agents — mostly Claude Code.
Claude Code plugins — installable via my plugin marketplace:
- professional-twin — Build and use a personal repository of your professional self (identity, history, values, direction) to support job applications, interviews, and career reflection
- tutor — Personal adaptive learning plugin. Create a custom course on any topic and study it through guided, expert-tutor-style sessions inside Claude Code
Parallel worktree tooling — running multiple AI coding sessions across isolated branches:
- orfoni — Desktop app for managing parallel terminal sessions across git worktrees (Rust / Tauri v2 / Svelte 5)
- worktree-dashboard — Terminal UI for monitoring worktree sessions and dev servers (Python)
- worktree-orchestrator — Claude Code skill for spinning up and managing parallel worktree sessions
Standalone Claude Code skills:
- rebase — Automatic branch rebasing with intelligent merge conflict resolution
- lazarus — Windows tray app that resurrects per-topic working environments — every app, every monitor, every virtual desktop, one click (Rust)
Production-ready starters for full-stack apps:
- flutter_bootstrap — Flutter web + Dart backend + GCP Cloud Run + Cloudflare Pages, wired with CI/CD and OpenTofu
- flutter_bootstrap_multi_user — Adds Google OAuth, Row-Level Security, and email allow-list
- flutter_bootstrap_multi_tenant — Adds multi-tenancy on top of the multi-user template
I build tools for people who do real work outside — drone operations, hunting, field coordination. All built with Flutter, designed offline-first.
- Scout — Drone mission management for fawn rescue. Live telemetry, team coordination, offline-first.
- WaidPlan — Digital hunting ground management with interactive maps, wildlife tracking, and weather data.
- Suchensieger — Training companion for German hunting dog exams (BH/VT, QBP, BLP/R, Working Tests). Log sessions, track skills, identify gaps.
- Calfred — Shared availability scheduling without the back-and-forth.

I coordinate fawn rescue drone missions with 70 volunteers across southern Germany — 175 missions, 1,700 hectares, 90 fawns saved last season. I also fly the drones.
