* Senior Full-Stack Developer Wanted: Build the MVP for PRESTIA AI
We are seeking an elite, execution-focused Senior Full-Stack Developer to build the Minimum Viable Product (MVP) for PRESTIA AI—a high-converting SaaS platform featuring a dynamic sales, payment, and post-purchase upsell engine.
* Required Tech Stack
We maintain strict engineering standards. You will develop directly on our infrastructure using:
Framework: Next.js 14 (App Router) + TypeScript
Styling & UI: Tailwind CSS (Unified, high-converting interfaces with full RTL/English support via next-intl)
Database & Backend: Supabase (PostgreSQL, Auth, RLS, Webhooks)
Payments & Billing: Stripe (Checkout, Tokenization/Setup Intents, Webhooks) + PayPal Vault
Hosting & Version Control: Vercel + GitHub (Direct execution on the owner's accounts)
Note: WordPress, Elementor, Bootstrap, or pre-built legacy templates are strictly prohibited. We build modern, serverless web applications.
* MVP Scope of Work
1. High-Converting Page Architecture (3 Core Layouts)
Landing & Solutions: Home Page + Core Solutions Showcase.
Sales Funnel Engine: Pricing + Checkout + Multi-Step Upsell/Downsell + Thank You Page.
Legal & Compliance: Dynamic Legal Pages Template (Terms, Privacy, Refund Policy).
2. Plans & Subscription Management
Configure 3 core subscription tiers (Starter / Growth / Enterprise).
Support for flexible Monthly / Yearly billing cycles in USD.
3. Dynamic Sales & Checkout Engine
Order Bumps: Program 3x distinct, real-time Order Bumps directly on the checkout screen.
1-Click Post-Purchase Upsells: Build a dynamic upsell/downsell engine supporting sequences of up to 10–15 steps without re-entering card details (leveraging Stripe Tokenization / Off-Session Payment Intents).
4. Integrations, Security & Backend
100% server-side payment processing and robust Stripe webhook event handlers.
Secure Supabase synchronization for accounts, order histories, and active subscription state management.
* Delivery & Quality Standards
Environment: Direct commits and deployment on our official GitHub repository and Vercel project.
Documentation: Clean, modular TypeScript code with a clear README.md explaining setup and architecture.
Verification: A 5–10 minute Loom video walkthrough proving test purchases, 1-click upsell routing, and secure Stripe webhook processing in test mode.
* Payment Milestones & Warranty Terms
Payments will be released via escrow structured across 3 core milestones:
