Front-End API Integration Expert for SaaS

We’re building a premium SaaS platform for TCF Canada speaking exam prep and are seeking a front-end integration expert to support and test API functionality in Webflow.

We already have:

  1. A UX designer building the layout and page structure.

  2. A backend developer handling Supabase, Stripe, GPT-4o, and Whisper logic.

Now, we’re looking for someone to:

  1. Test front-end API connections (login, Stripe, exam logic, feedback display, etc.)

  2. Collaborate closely with the backend developer to ensure all AI, exam, and Stripe logic integrates smoothly.

  3. Occasionally create or modify Webflow pages only when needed (most are already designed).

  4. Confirm that Webflow elements properly accept and display the coded logic and data from the backend.

  5. Troubleshoot front-end issues and communicate clearly in our shared Slack/Notion workspace.

You must have experience in:

  1. Webflow

  2. JavaScript fetch integration

  3. REST API testing and debugging

  4. Working with backend dev

Bonus: AI integration testing (GPT or similar)

We’ll be sending code snippets for you to test live in Webflow. Starting immediately.
