- We are developing GRAIL – Green Revolutionary Alliance for Infrastructure & Life – a mobile platform that rewards eco-friendly behavior with a unique digital coin. The app allows users to earn GRAIL Coins by proving sustainable actions (e.g., using solar, recycling, reducing water/electricity waste), which they can spend in a marketplace of green products and services.
We are looking for a Flutter + Firebase developer (or full-stack mobile app builder) to help us build the MVP, including:

Payment Terms:
We are an early-stage startup currently pre-revenue and unfunded. We are looking for a developer willing to accept full payment once the app is launched and starts generating revenue. You will be listed as a VIP Partner in the app and get priority for future paid updates and features.
