Bubble Developer Needed- Modern Web App

I am building a modern, tech-forward gifting platform called Giving Pals.
The platform will allow users to:
• Search for a charity
• Make a donation
• Personalize a digital card (API integrated)
• Complete payment via Stripe
• Receive a dynamically generated card image
This is an MVP build with strong focus on:
Clean, minimal, modern UI (Notion-style aesthetic)
Efficient backend workflows
Stripe integration (including webhooks)
External API integrations
Workload unit optimization
Referral tracking logic
Core Technical Requirements
• Strong Bubble experience (2+ years preferred)
• Stripe Checkout + webhook implementation
• API Connector experience (REST APIs)
• Backend workflow structuring
• Database schema design
• Mobile responsiveness
Important Optimization Requirements
• Live preview of the card must NOT trigger external API calls
• External image generation should occur only once, after confirmed Stripe payment
