Project description:
"Job Description

We are building GymLead, a lightweight SaaS platform for gyms and personal trainers.
The product provides an embeddable JavaScript chat widget that captures leads on WordPress websites and delivers them via email.

We are looking for an experienced developer to build the MVP, not a full-scale SaaS.

Scope of Work (MVP)

You will build a minimal but production-ready system that includes:

User authentication (email/password)

Stripe subscriptions (€75/month recurring)

Subscription enforcement (inactive = widget disabled)

Simple customer dashboard:

Business name

Accent color

Notification email

Welcome text

Copyable embed code

JavaScript embeddable widget:

Bottom-right chat bubble

Click to open/close

Multi-step lead form

GDPR consent text

Hosting & deployment (Vercel or similar)

This is not a chatbot builder and not an AI-heavy project.

Tech Preferences (Flexible)

Frontend: React / [login to view URL]

Backend/API: Node.js

Database/Auth: Supabase, Firebase, or similar

Payments: Stripe

Email: SendGrid / Resend

Hosting: Vercel

You are free to propose alternatives if justified.
