I did a PhD in theoretical physics. String theory, quantum deformations, 3 published papers. Then I left academia and started building things.

Now I build AI agents and automation systems for marketing agencies. Copy engines trained on your brand voice. Cold email machines. Content multipliers. Currently working with four agencies across DACH and the EU through Dark Gravity Labs.

Before that I built ML systems that reconstruct 3D pipeline geometries from magnetic field data. That work ended up at BP, Shell, Chevron, and NATO — over 10,000 km of pipelines inspected.

If you’re doing something manually that a machine should do, I can probably fix that.

What I’ve built

AI Copy Engine for Winestreet Media — Brand-trained AI copywriting agents for Marc Roth’s VSL agency. Used daily by his creative team. First-draft time cut in half.

Reporting automation for Playstack — One-click reports with YouTube API integration for Milan Smets’s growth agency. Per-client reporting went from 3 hours to 3 minutes. Client retention jumped from 4 to 6+ months. ~$35K in additional revenue from that one change.

Agent infrastructure for The Other Side — Claude Code and OpenClaw deployment for Tas Zacharis’s agency. Slack integration, voice-based task delegation, automated workflows across the team.

ML pipeline inspection — 3D reconstruction from magnetic field data for BP, Shell, Chevron, NATO. First-ever underwater pipeline inspection capability.

Demoscene visuals — Custom 3D rendering engine compressed into 64 kilobytes. Won competitions.

The physics papers, if you’re curious:

• The twisted story of worldsheet scattering in η-deformed AdS5 × S5
• On quantum deformations of AdS3 × S3 × T4 and mirror duality
• Do Drinfeld twists of AdS5×S5 survive light-cone quantization?

Side projects

Portrait Photography — I shoot portraits with strong conceptual themes. Keeps me creative outside of code.
