Full-Stack Developer — Customer Dashboard, Payments & API Integration

"About the Project" This is a tree-planting platform focused on verified planting and impact tracking. I'm building the marketing website myself in Framer. What I need now is a developer to build the web app portion: the customer dashboard, payment flow, branded email automation, and blockchain API integration. UX/UI design will be provided by me — this role is pure development/implementation, not design. Reference WebApp: https://app.zeroco2.eco/ "Scope of Work" - Payment flow: Integrate Authorize.net (powered by Chase) using the hosted checkout option. Users select a project/tree option, proceed to checkout, complete payment via Authorize.net's hosted payment form, and receive confirmation. No custom payment processor needs to be built — this is an integration, not a build-from-scratch payment system. (Refs: authorize.net/developers.html, developer.authorize.net, Chase ecommerce payment gateway docs) - Customer dashboard: A simple, logged-in dashboard (separate from the blockchain integration itself) where users can view the number of trees they've planted and see project impact updates. A detailed reference doc ("Customer-Facing Dashboard & Payment Process") describing the intended layout and content is available and will be shared with shortlisted candidates. - Blockchain API integration: Connect to our blockchain technology partner, Chainparency, via their existing API (documentation available) to pull tree traceability / verification data (e.g., tree tracking, verification details, blockchain reference IDs) into the dashboard. This is a third-party API integration, not building blockchain infrastructure from scratch. - Branded transactional emails: Set up automated, branded email flows (order/payment confirmation, tree-planting updates) using an existing tool/platform (e.g., MailerLite, Mailchimp, Klaviyo, Loops, or similar) rather than custom-built email infrastructure. - Authentication & account features: Basic user login/account system to support the dashboard experience. "What's Already in Place" - Blockchain/traceability backend already built and maintained by Chainparency (you'll integrate with their API, not build it) - Reference documentation for the dashboard/payment flow and the Chainparency API NOTE: Please include your estimated timeline and budget range for this scope in your application
