Bubble Developer Needed to Build PDF Markup MVP / Prototype

Description

Project DescriptionI’m looking for an experienced Bubble developer (or no-code expert with frontend and JavaScript experience) to create a rapid prototype (MVP) of a web app that allows users to upload, view, annotate, and measure scaled PDF drawings.
This tool will be used to test and validate a concept within the construction and design industry. It does not require final polish—just a functional prototype that allows for early user testing.
Key Features Needed in the MVPUpload and display PDF drawings
Annotation tools: pen/freehand, arrows, highlighter, eraser, text, shapes
Add comment pins with threaded replies
Calibrate measurement scale: user selects two points and inputs real-world distance
Input drawing scale and measure off the PDF accurately
Save and/or export marked-up version of the drawing
Clean, simple UI with intuitive layout
DeliverablesWorking prototype built in Bubble (or similar no-code platform)
Basic responsive interface with functional measurement tool
Ability for users to test key features as described above
TimelineLooking for delivery within 3–5 weeks from project start
Ideal start: as soon as possible
BudgetPlease submit a proposal with your quote (fixed price or hourly) and your estimated delivery timeline. The minimum budget will be honoured and adjusted appropriately based on your experience and the complexity involved.
What I Can ProvideExample interface layout (mockups provided)
Sample PDFs for testing
Clear feedback and direction throughout the project
