Dennis Decoene

Builder. Tinkerer. Pragmatist.

West-Flanders based. I work at the intersection of systems thinking and making things that actually run.

What I'm building

• WebBaseIII — A dBASE III clone rebuilt for the browser. TypeScript interpreter, WebSocket/Node backend, WAL-mode SQLite. Per-session isolated executors. Architecturally superior to the original's shared-file model. Because some ideas deserve a proper second life.

• rgwnd — Wind-optimized cycling route planning for the Belgian knooppuntennetwerk. Built for the rider who treats headwind as a variable, not a surprise.

• Taperwise — Deterministic medication tapering calculators for clinicians. No AI. No hallucinations. Just math that doesn't kill people.

How I work

Self-hosted on Hetzner. Docker Compose, Caddy, Tailscale. I assemble existing tools over building new ones when that's the honest answer. I have a bias toward shipping things that work over announcing things that might.

18 years of Microsoft Dynamics NAV/Business Central in a past life. Still useful. Not the whole story.

Outside the terminal

Daily 30km on a non-electric bike. Working toward building custom steel bicycle frames — fillet brazing, laser-cut dropouts, the whole thing. Somewhere between hobby and slow-burn second career.

Also: Latin (Familia Romana), algorithmic music (Strudel/TidalCycles, dark warehouse techno), and a philosophy paper that keeps getting longer.
