Senior React Developer (Node.js, Next.js, Python, AI) - Early-Stage AI Project

We're building an AI-powered product from the ground up and looking for an experienced React Developer with strong Node.js and Next.js skills to join us at an early stage. What we need: - Solid hands-on experience with React, Node.js, Next.js - Python experience for AI/backend logic (FastAPI, Flask, or similar) - Experience integrating AI/LLM APIs (OpenAI, Anthropic, Claude, etc.) — required - Comfortable working with AI-driven features: chat interfaces, agents, RAG, prompt-based workflows, etc. - Ability to move fast on an MVP and iterate based on feedback - Clean, scalable code — we're building for the long run, not just a prototype Who we're looking for: We prefer working with an agency or a team that can support and scale the project long-term after the initial build. This is an AI product with ongoing development ahead — long-term collaboration is a priority, not a one-off gig. Early stage Long-term potential, ongoing support expected If you or your agency have experience building AI-powered products end-to-end (frontend + Python backend), we'd love to hear from you. Please include relevant AI/LLM project examples in your proposal.
