I need full stack developer to Join build a carbon credit app

We’re building a carbon credit application called SikaFields — a mobile and web-based platform that empowers smallholder farmers across Africa to participate in carbon removal initiatives. The app allows farmers to register their farms, log sustainable practices (e.g., agroforestry, regenerative agriculture), and receive AI-driven guidance. It tracks carbon impact through verified logs and rewards farmers with carbon credits or tokens.

Tech Stack:

Frontend: React.js (Web), React Native (Mobile)

Backend: Node.js with Express.js

Features: Geo-tagged farm mapping, photo/voice log uploads, AI recommendations, credit tracking, and reward redemption.

We're looking for a freelancer to support us in developing core modules, ensuring a smooth user experience, and integrating third-party APIs for carbon estimation and rewards.
