Finalize Legal Notice Generator: PDF + Signature

Need Expert to Fix Final PDF Output + Signature Overlay for Legal Notice Generator (React + Flask)



I’m developing a Legal Notice Generator web app using React (Vite + Tailwind CSS) on the frontend and Flask + WeasyPrint + PyMuPDF on the backend. Most of the work is already done, but I need a professional developer to help complete the final pending tasks related to PDF generation, signature overlay, and preview before download.

Signature upload with transparent PNG support

Proper layout with header, footer, and watermark

Final preview route implemented using Flask

PlacedElements (signature drag-drop with rotation) working on frontend

Tasks You Need to Complete:
Generate Final PDF

Clean, professional layout

Header (logo + current date), footer (branding)

Rotation and scaling preserved

PNG transparency must be maintained
