BEHIND THE WORK
I'm Guus.
I like building the whole path: from messy inputs and underlying models to something clear enough to use.

Independent work
My projects span research tools, retrieval systems, health information, music, and games. Re-Search brings several of those interests together: preserving useful reasoning as a project moves from exploration into action.
