Hi there, What exactly should the AI generate, and does each user need private context/history or only one-off generation from the current input? For subscriptions, do you already have Stripe pricing/tiers defined, including usage limits, credits, or feature access per plan? This is a strong fit because the main challenge is connecting auth, billing, AI usage, database state, and permissions without creating a fragile MVP. I would build the core SaaS flow first, then harden it for production with clean API boundaries, usage tracking, admin controls, and reliable error handling. A similar challenge involved an AI SaaS with user accounts, paid plans, OpenAI generation, dashboards, and admin tools. The difficult parts were failed Stripe webhooks, duplicate AI requests, usage-limit enforcement, and keeping tenant data isolated. Solved it with verified webhooks, idempotent jobs, server-side access checks, usage metering, PostgreSQL constraints, and audit logs. Several years as a senior software engineer plus around three years as an Immunefi security auditor make [login to view URL], Node/Python, PostgreSQL, Supabase, OpenAI, Stripe, and secure SaaS architecture familiar ground. Ready to start immediately. Best, Hlib

For this MVP, I propose a paid first phase of 8 hours to deliver a working core platform with NextJS, user authentication, a PostgreSQL database, and the primary OpenAI generation endpoint. As concrete proof, I built a multi-tenant CRM with NextJS, TypeScript, PostgreSQL and Cloudflare Workers, including team permissions, history and automation. Stripe subscription management, admin dashboard analytics, and production deployment are excluded from this initial milestone and reserved for subsequent phases. What specific AI generation workflow or prompt output should this initial core focus on?

Hi there, I’d love to help make this project a great success for you. This project is a strong match for my background in full-stack development, backend systems, APIs, databases, automation, and AI integration. I can build the MVP with a clean architecture that is easy to extend as the product grows. My approach would include: - Secure user authentication and role management - Stripe subscription and billing workflows - OpenAI-powered generation features - User dashboard with usage/history - Admin dashboard for users, plans, and activity - PostgreSQL/Supabase database design - REST API backend in Node.js or Python - Usage limits and subscription enforcement - Error handling, logging, and basic analytics - Deployment to Vercel/AWS - Clean source code and documentation I’d recommend building the MVP in clear milestones: auth/database first, then AI generation, billing, dashboards, and deployment. Could you share the exact AI generation workflow you want in the first version—for example text, images, documents, or something else? Best regards, Jeremy

I'd have Stripe webhooks write each subscription straight into a Postgres table, so the app always knows someone's plan from its own database. Generation limits can hang off that same row - a free tier gets a handful a month, paid gets more - and the admin dashboard reads from it too On the Supabase side, row-level security on every table, so a user's generations are only ever visible to them For the OpenAI part I'd use structured outputs, so whatever comes back drops into the dashboard as clean fields instead of one blob of text I've wired Stripe billing and LLM features into web apps before What will the AI actually be generating - text, images, something else?
