SaaS developer|Full Stack Developer Next.js|Supabase MVP development

🚀 PropRadar went from zero to live in 8 weeks, built solo. As a SaaS Developer, Next.js Developer and Full Stack Developer React specialist I build MVPs the same way: Next.js, Supabase, Stripe and AI, with a deployed demo at every milestone. Top Rated. ✅ I'm a Senior Full Stack Developer, React Developer, Next.js Developer and SaaS Developer who owns the product from database to deployment. In MVP development that means software investors can click through, not just a pitch deck. 📊 PropRadar (Dubai off-plan): 24 projects compared with ROI and investment grade. 💳 Stripe affiliate program: 14-day cookie attribution, 14-day commission hold. 👥 Lovable takeover: 25 users on maintainable code. ⭐ 5 stars on my largest build, 100% Job Success, replies within 1 hour, 7am-5pm ET. As a React Developer, Next.js Developer and Front End Developer I build dashboards, web apps and customer portals with Next.js, React.js, TypeScript and Tailwind CSS: a next.js tailwind setup with a Responsive UI. As a Nextjs Developer, React JS Developer and full stack react developer I keep components small and rendering fast. Full stack next.js and front end developer next.js work keeps pages, API routes and data in one codebase, so React web development and React development stay maintainable. A react web developer on fullstack web developer projects gets readable nextjs frontend code. As a Backend Developer, Node.js Backend Developer and Back End Developer Node.js, I build REST API layers with Node.js, Express, ExpressJS and NestJS: authentication, payments, integrations and webhooks. A Next.js Developer who writes the API closes the front/back end gap (node.js next.js, nextjs nodejs). Prisma next.js, nextjs strapi and django nextjs setups fit existing CMS or Python services; a backend developer nest.js approach keeps big APIs organized. Supabase is my core backend: Postgres, RLS and Auth. As a SaaS Developer, Next.js Developer and Full Stack Developer Supabase React specialist I build multi-tenant data models on supabase postgres for MVP development: next.js supabase and react next supabase ai aws apps, postgresql supabase javascript rest json endpoints. I automate with n8n supabase, turn v0 supabase and flutterflow supabase prototypes into production, handle supabase bubble migrations, and pair Supabase with React or Svelte. Stripe is where MVP development breaks, so as a Full Stack Developer React Node engineer I build it carefully: Checkout with Product and Price IDs, subscriptions, webhooks, stripe dispute events, affiliate attribution and commission tracking. As a Nextjs Developer and React Developer I build the checkout UI too. Bubble stripe, wix stripe and swiftui stripe projects need the same fixes: Price IDs and payment-confirming webhooks. As an AI app developer and Open AI developer I add OpenAI and Claude to real products: assistants, summaries and AI workflows with usage limits tied to Stripe plans. As an AI chatbot developer and AI software developer I build the chat UI, history and permissions around the model; as a Full Stack Developer AI and full stack ai saas developer I also handle auth, billing and deployment. As a SaaS Developer and Nextjs Developer I stream answers into the UI and keep AI inside MVP development scope. Many AI developers stop at the demo; I ship. Founders hire me as one owner: a SaaS Developer who plans the MVP development, a Full Stack Developer React Node engineer who builds it, a Next.js Developer React Develope and Nextjs Developer for the interface, and a who keeps it fast. As a Senior Full Stack Developer React builder I take MVP development from scope to launch with fixed-price milestones, and I take over half-finished apps from Lovable, Bolt, Cursor or v0. Also in scope: Full Stack Developer React apps (full stack node.js react,react developer firebase full stack developer react firebase,),MongoDB or Postgree data, e-commerce checkout, mobile apps on the same Supabase backend (React Native developer path), and SaaS marketing pages with affiliate links for a social media manager. Web developer, app developer and mobile app developer teams can add an API integration partner and Nextjs Developer here. Teams searching for a backend developer, Laravel backend developer, Python developer, PHP backend developer, Java backend developer, WordPress backend developer, Django backend developer, AI backend developer or backend app developer often need a Nextjs Developer for billing and API integration. Also full stack developer PHP, Shopify backend developer,full stack developer Laravel, WordPress developer, full stack developer Shopify and Python full stack developer briefs, full stack developer SaaS and B2B SaaS booking system developer projects. Send me what you're building and where it's stuck. I'll reply with a short plan and the first thing I'd change. Hired as: SaaS Developer,MVP developmenе Full Stack Developer,Next.js Developer, React Developer, Nextjs Developer React 05.11
