Homelane's order and finance flow was a PHP monolith bolted onto a 3D room designer. Contract scope was to migrate the order surface to React without breaking the live transactional pipeline, and then prototype a 3D-to-PDF export for vendors.
Migration
Slice-by-slice rewrite — one route group at a time, shared header + auth via an iframe-free bridge so PHP and React could coexist while the cutover happened. Took a quarter; no revenue downtime.
3D-to-PDF POC
Three.js scene → an off-screen orthographic camera → vector-traced via a tiny custom rasteriser → into a PDFKit document with vendor-friendly dimensioning. Designers loved it. Never made it past POC because the company pivoted shortly after.
