Full-Stack Developer for AI-Powered Content Platform

We are looking to develop an AI-powered content platform that allows users to generate, edit, and manage written content (articles, blogs, social posts) using LLMs (e.g., GPT, Claude, or open-source models). The platform should include user authentication, a text editor with AI prompts, content history, and API key management. Core requirements: Frontend: React/Next.js or Vue (clean, responsive UI with a rich-text editor like TipTap or Slate) Backend: Node.js (Express/Nest) or Python (FastAPI/Django) AI integration: Experience with OpenAI API, Anthropic, or local LLMs (e.g., Llama via Replicate or Ollama)
