I build websites, web and iOS apps, and tooling for AI coding agents – freelance, for companies and teams, remote from Germany. German and English.
| Project | What it is |
|---|---|
| NilCore | Go coding agent where a verifier, not the model, decides when work is done |
| RanA | Kernel-level, tamper-evident flight recorder for AI agents (eBPF, signed ledger) |
| CrustCore | Compact Rust verifier kernel: completion, approvals and secrets as types that cannot be faked |
| ThinClaw | Self-hosted AI collaborator with lasting identity, memory, routines and policy-gated tools |
| Pines | Local-first AI workbench for iPhone and Apple Watch on MLX Swift (preview) |
| SEO Polish Workflow | Evidence-bound SEO and agent-readiness audits for live websites |
| AtlasCore | Governed data layer that turns approved sources into cited evidence for agents |
Merged pull requests in Apple's MLX Swift and MLX Swift LM.
