Full stack developer

Looking for a full-stack developer to join Ecomify as a co-builder — equity and revenue share on the table. Ecomify is an all-in-one operating system for ecommerce founders. AI video ad creation, competitor intelligence, multi-platform ad management, Shopify store building — one product instead of six subscriptions. We're about 30% built on a clean Next.js 14 + Supabase + Prisma stack and moving toward launch. Here's what still needs to be done: Landing page polish and animation work. Stripe billing, credit metering, plan enforcement. API integrations across ElevenLabs, fal.ai video models, Meta Marketing API, TikTok, Google, and Pinterest Ads. Command Center analytics and campaign management. AI Spy competitor intelligence. Shopify OAuth and Store Builder. MCP server for Claude integration. The stack: Next.js 14 App Router, TypeScript, Tailwind CSS, Supabase, Prisma, Stripe, fal.ai, Vercel. This isn't a standard contractor gig. We already have a technical co-founder. We're looking for someone who wants to build alongside us and share in what we're creating — the right person gets equity and revenue share on top of the base arrangement. You're the right fit if you've shipped real Next.js apps with third-party API integrations, you can read an existing codebase without needing to rewrite it, and you work well from a detailed spec without constant back and forth. Send me something you've built that's relevant and tell me why this interests you. GitHub or a live product beats a long cover letter every time.
