Lead-Gen Funnel Developer with API Integration

Project Summary

I’m hiring a detail-oriented Webflow developer to build a high-converting lead-gen funnel that gives homeowners a low-to-high cost range for their window + door replacement project, captures their info, and displays results instantly.

This is not a full custom app—the backend already exists. Your job is to build the Webflow front-end and connect it cleanly to an existing Cloudflare Worker API.

Scope (What You’ll Build)

Pages (Webflow):

Home (conversion-focused landing page)

Estimate (calculator/questions + lead capture form)

Results (renders the dynamic low/high range + project details)

Core Functionality (critical):

Build the Estimate form with exact element + input IDs provided in my spec (no deviations)

Add lightweight custom JavaScript that:

validates required fields

POSTs the form data to my existing Cloudflare Worker API

routes the user to /results with a lead/reference

displays the returned low/high cost range + key outputs into specific Results-page elements (by ID)

Tracking (must be verified):

Install Google Tag Manager + GA4

Configure + test Google Ads conversion tracking for “Lead Submitted” (should fire only on successful submissions)

Definition of Done (Non-Negotiable)

Pixel-accurate to my provided mockup/layout and clean, modern UI

Fully responsive (mobile + desktop)

End-to-end flow works: Webflow → API → Results display

Leads successfully captured/stored (verified via test submissions)

GA4/GTM + Ads conversion events tested and firing correctly

Clean handoff: Webflow project organized + documented custom code locations

Ideal Candidate

Strong Webflow portfolio (high-fidelity builds)

Comfortable with JavaScript + API integration

Highly detail-oriented (ID accuracy matters)

Conversion-minded (clear UX, clean form behavior, no sloppy edge cases)

To Apply (Required)

Send 2–3 Webflow examples where you matched a mockup closely

Confirm: “I can implement exact form/input IDs with zero changes.”

Screening Question:

In 1–2 sentences, explain how you will connect a Webflow form to an API endpoint and then render the returned estimate range on a Results page.

Notes: I will provide the mockup, one-page spec (IDs/endpoints), and test instructions upon hire.
