Founding Engineer / Full-Stack Builder

I'm building Interview Strategist™, an AI-powered career strategy platform built around the Interview Strategist Method™:Understand how hiring decisions are made.Stop being evaluated. Start influencing.Important upfront clarity ? This is not a salaried role ? This is not a funded company (yet) ? This is a build-for-upside opportunity with EBITDA participation and exit upsideIf you enjoy building real products with real users—and sharing the upside—this may be for you.What you'll buildInterview Strategist™ is a web-based SaaS platform integrating LLM / ChatGPT-type models into structured, decision-driven user journeys.A modern full-stack web applicationStructured AI workflows (not just chat)A clean, scalable, and well-documented architectureA system that can be maintained or extended by others if neededCore technical scopeFrontend: React / Next.js (or equivalent modern framework)Backend: Node.js or Python (FastAPI welcome)Integration of OpenAI / LLM APIs into production workflowsUser authentication, core flows, dashboardsCloud deployment (AWS / GCP / Vercel or similar)Version control, documentation, and basic DevOps hygieneYou don't need to be an AI researcher—but you should be comfortable turning LLMs into real product logic, not just demos.Expected experienceThis role is well suited if you:Have already built and shipped web productsAre comfortable owning a system end-to-endUnderstand (or are eager to master):API-driven architecturesPrompt-based workflowsCost / performance trade-offs with LLMsEnjoy autonomy, speed, and responsibilityProfiles that often fit wellStrong junior to mid-level full-stack engineersEngineers between rolesFreelancers looking for ownership rather than billing hours??
