Full Stack Senior Developer

Senior Full-Stack Developer: AI Platform (Project-Based) I'm building a multi-platform AI product. Web app, mobile app (iOS + Android), and desktop app. There's also an advertiser-facing portal and an internal admin dashboard. The backend is already partially scaffolded. The foundation is there. What I need is someone who can take it to production-ready, not a demo, not an MVP, not something you click around once and move on. A real, working product that real users can use. Im business/ finance oriented not technology oriented, looking for someone who can fill that gap What I'm looking for: Someone who has shipped real products before. Not tutorials. Not client work that never went live. Actual production applications with real users. I'll want to see it. You need to be comfortable across the full stack... backend APIs, frontend implementation, mobile, infrastructure setup, and deployment. If you're strong in most of these and honest about where you need support, that's fine. If you're going to tell me you can do everything and then disappear for two weeks, don't reach out. UI/UX design direction is already handled separately. You'll be implementing designs, not creating them from scratch. Before you reach out: Send your portfolio. Specifically show me something you built that went live and had real users. GitHub links, live URLs, or a short walkthrough, whatever shows me it's real. No portfolio, no response. NDA: Before we get on a call or I share any details about what this product actually is, you'll need to sign an NDA. It's straightforward and non-negotiable. If that's a problem, this isn't the right fit. Pricing and timeline: This is project-based. I'm not looking for hourly (though a retainer or hourly could apply after the project is done to keep you around). I want to know your total price to take this to a production-ready state and your realistic timeline to get there.
