Floor Plan Creator System
A web-based editor for architectural floor plans on a custom SVG + Canvas engine — grid snapping, undo/redo, rotation and multi-floor layers over a 1,100+ component catalogue, with lossless XML import/export and PNG/JPEG output. A Turborepo monorepo whose drawing engine is shared with a DDD/CQRS NestJS API, plus real-time single-session security over SSE.
