How to build a freelancing platform in Bubble

Go to the Data tab and create the following Data Types. User (built-in) — add fields: role (text: Client or Freelancer), display_name (text), bio (text), skills (list of texts), hourly_rate (number), profile_image (image), rating (number). Project — fields: title (text), description (text), budget_min (number), budget_max (number), category (text), skills_required (list of texts), client (User), status (text: Open, In Progress, Completed, Cancelled), deadline (date). Proposal — fields: freelancer (User), project (Project), cover_letter (text), proposed_rate (number), estimated_days (number), status (text: Pending, Accepted, Rejected). Milestone — fields: project (Project), title (text), amount (number), status (text: Pending, In Progress, Completed, Paid), due_date (date). Review — fields: reviewer (User), reviewee (User), project (Project), rating (number), comment (text).

Create a page called post-project. Add Input elements for title, a Multiline Input for description, Number Inputs for budget range, a Dropdown for category (populated from your Category Option Set), a Tag Input or multi-select for required skills, and a Date Picker for deadline. Add a Post Project button. Create a workflow: When Button Post Project is clicked → Create a new Project with all form values, client = Current User, status = Open. After creation, navigate to the project detail page. On the browse page, add a Repeating Group showing all Projects where status = Open, sorted by Created Date descending.

On the project detail page, add a Submit Proposal section visible only when Current User's role is Freelancer AND the project's status is Open. Include a Multiline Input for the cover letter, a Number Input for the proposed rate, and a Number Input for estimated days. Add a Submit Proposal button. Create a workflow: Create a new Proposal with freelancer = Current User, project = Current Page's Project, and form values, status = Pending. Show a confirmation message. On the client's project page, display all proposals for their project in a Repeating Group with each freelancer's name, rating, rate, and cover letter.

In the proposals Repeating Group on the project page, add an Accept button in each cell (visible only to the project's client). Create a workflow: When Accept is clicked → Make changes to Current cell's Proposal: status = Accepted. Then Make changes to Current Page's Project: status = In Progress. Also add a step to reject all other proposals: Schedule API Workflow on a list of Do a search for Proposals where project = this project AND status = Pending, changing each status to Rejected. Send a notification to the accepted freelancer (create a Notification data type or send an email).

On the active project page, add a section for milestones. Create a form for the client to add milestones: title, amount, due date. Create a workflow to Create a new Milestone with project, title, amount, due_date, and status = Pending. Display milestones in a Repeating Group. Add Mark Complete button (for freelancer) and Approve & Pay button (for client). When the freelancer marks complete, change status to Completed. When the client approves, integrate Stripe to process the payment amount and change status to Paid. For the MVP, you can track milestones without actual payment processing.

After a project is marked Completed (all milestones paid), show a Leave Review section to both the client and freelancer. Add a star rating input (1-5 stars using an Icon Repeating Group or radio buttons) and a Multiline Input for the review comment. Create a workflow: Create a new Review with reviewer = Current User, reviewee = the other party, project, rating, and comment. After creating the review, update the reviewee's overall rating field using a calculation: Do a search for Reviews where reviewee = this user's rating:average. Display reviews on user profiles.
