BallR
Public project Tobias is building end-to-end — pickup football app, dashboard and a small community layer.
- Full stack, built by Tobias: product, design, growth and tech
- Focus: local match discovery and the player community around it
Portfolio
Current projects.
The live projects now have one ordered domain family: BallR, meOS and DJ Dopamine under tobiki.de.
BallR
One of the public projects: football pickup app, dashboard and a small ecosystem around it.
DJ Dopamine
AI music tool, live. Turns a reference song into a new one.
meOS
Personal operating system. Daily execution, goals, habits, AI coach.
More in progress
Smaller AI tools and experiments, not public yet.
DJ Dopamine
Uses Meta's TRIBE-style audio analysis to read the reaction a song creates, then tries to recreate that feeling in a new track.
- Public experiment, end-to-end AI flow
- Built to scan a track's emotional response and recreate it in a new one
meOS
Personal operating system for daily execution — habits, check-ins, goal hierarchies from values down to weekly targets, plus an AI coach on top.
- Goal hierarchy from values to weekly tasks, plus daily check-in and habit points
- Web app with cloud AI, sync, mobile PWA and desktop access
- Built for Tobias first, then generalized — he runs on it himself
Get involved
If one of these fits.
Short intent signals, not long forms. Each button opens a small note you can send in one click.
Back an early project
Small tickets welcome. AI tooling and early project work are the obvious candidates.
Co-founder
Open to one. Ideally someone technical, distribution-strong or with a domain edge. Not looking for more generalists.
Work together
Freelance, embedded or full-time. AI-leaning marketing, product work, internal tools.
