Mobile App Developer: AI Agent, iOS & Android, React Native, Flutter, FastAPI, Azure AI, Claude, AWS

I’m looking for a Mobile App Developer to build one AI Agent feature for an existing iOS & Android application. The main focus is bringing an AI-powered workflow into a real mobile product - from the mobile UI and API integration to the AI Agent logic behind it. I primarily work with React Native and Flutter, so strong experience with one or both is important. The feature should work reliably across both iOS and Android, with clean mobile UX and proper handling of authentication, API requests, loading states, errors, and asynchronous AI operations. On the AI side, the feature may involve Claude or Azure AI, with a FastAPI backend connecting the mobile application to the AI workflow. Depending on the implementation, the agent may use LangChain, LangGraph, RAG, or similar approaches. What you’ll work on - Build an AI Agent feature for an existing mobile application - Develop the mobile side using React Native and/or Flutter - Support both iOS and Android - Build or integrate a FastAPI backend - Integrate Claude and/or Azure AI - Implement AI Agent workflows and LLM interactions - Connect the feature to existing REST APIs and application data - Handle authentication, validation, errors, and asynchronous processing - Add appropriate mobile states for AI processing and responses - Test the feature across iOS and Android - Dockerize the backend and prepare it for AWS deployment Ideal experience You have hands-on experience building production mobile applications with React Native or Flutter and have integrated AI functionality into real products. Experience with AI Agents, Claude, Azure AI, OpenAI, FastAPI, LangChain, LangGraph, RAG, vector databases, Docker, and AWS is highly relevant. I’m not looking for someone to build an entire AI platform from scratch. The goal is to take one well-defined AI feature from the existing product and turn it into a reliable, production-ready mobile experience. Good technical judgment matters here. I’d rather have a clean and practical implementation than an over-engineered architecture. If you’ve built an AI-powered mobile app, AI Agent, React Native or Flutter application with LLM integration, please share a relevant example and briefly explain your role in it.
