I’m launching a subscription-based platform that lets merchants accept cryptocurrency at checkout and automatically hand the order off to a last-mile delivery service. The full flow—from wallet payment to dispatch confirmation—has to feel as simple as any mainstream e-commerce experience; polished UX is the top priority. Scope • Customer-facing web app where shoppers pay with popular coins or tokens, see real-time rates, and receive instant confirmation. • Merchant dashboard to create stores, track orders, manage payouts, and configure delivery partners. • Admin area for plan management, analytics, and user support. • Secure crypto payment gateway with on-chain verification, webhooks, and automatic conversion options. • Delivery API integration (Bringg, Shippo, or similar) so paid orders raise delivery jobs without extra clicks. • Tiered subscription logic, metered usage tracking, and in-app billing. You’re free to recommend the stack, but a modern SPA front end (React, Vue, or Svelte) and a robust back end (Node, Go, or Python) that can scale quickly will be expected. Familiarity with Web3 libraries (ethers.js / web3.js), smart-contract interaction, and cloud deployment (AWS, GCP, or Azure with Docker/Kubernetes) is essential. Timeline I’d like to see an MVP ready for stakeholder testing as soon as possible, so we’ll iterate in short sprints and review progress frequently. What to include when you reply Share comparable SaaS or crypto payment projects you’ve shipped, the specific tech you used, and the role you played. A concise outline of how you would tackle the build and hit an aggressive launch date will help me move fast on a hire.
