Could you build this?
Partial A canvas with kanban, PDF signing, and simple spreadsheets is buildable with libraries, but faithful docx and xlsx editors plus a native-feeling infinite canvas are a very large scope.
What it would actually take: Use an infinite-canvas engine (tldraw or a custom WebGL/canvas renderer) and embed existing document engines (for example ONLYOFFICE or Collabora, or SheetJS/formula libraries for spreadsheets). PDF signing needs a PDF library such as pdf-lib or PDF.js. The hard parts are Office format fidelity, real-time multi-user collaboration, and the sheer breadth of features, which typically takes a team of experienced front-end and document-engine engineers.
