Speech AI,
agentic systems,
shipped solo.
Solo developer based in Eindhoven. Building production software at the intersection of local inference, real-time multiplayer, and multi-agent orchestration.
Four production projects, built solo.
Each shipped end-to-end: research, design, infrastructure, code, and operations.
TranscriptZ
Learn without watching.
Desktop application converting YouTube and long-form audio into actionable knowledge. Local Whisper transcription, speaker diarization, knowledge-graph extraction, and TTS rebroadcast — all on-device.
SnakeWars
Multiplayer skill game on Solana.
Competitive snake arena with on-chain SOL stakes, Colyseus-backed real-time infrastructure, and a skill-based PvP economy. Designed, built and deployed solo, end to end.
Disciplinr
Productivity OS for builders.
Task system with file-locking, multi-agent terminal coordination, local voice input, and AI-powered task scoring. Built for solo developers running multiple Claude Code instances in parallel.
GODFLOW
A team of agents, one engineer.
Multi-agent Claude Code orchestration: parallel Codex + Claude agents that cross-verify each other and gate every task on E2E tests. Benchmark run: 435 tests and 18 database tables shipped in 5h10m.
Built carefully. Shipped gradually.
Current focus is the SnakeWars launch. Public releases of TranscriptZ and GODFLOW follow, with the next product entering scoping after.
- 01 Foundation
Disciplinr shipped and in daily use. Task locking, multi-agent terminal coordination, local voice control. Foundation tooling for the rest of the work.
Completed - 02 Validation
TranscriptZ production builds proven on Windows, macOS and Linux. Local Whisper transcription pipeline validated end-to-end.
Completed - 03 Launch
SnakeWars pre-launch hardening. On-chain settlement, real-time multiplayer, anti-cheat. 90% complete and converging on first public release.
Current - 04 Public release
TranscriptZ public release with knowledge-graph extraction and TTS rebroadcast. Then GODFLOW orchestration framework open-sourced.
Following - 05 Next product
A new local-first speech application in early scoping. Direction confirmed after SnakeWars stabilises in production.

Working from a single machine. No team, no co-founders. Output is the argument.
I build the things I want to exist. Speech AI that runs on your machine. Multiplayer infrastructure that scales without a team. Orchestration layers that make one developer move like fifteen.
