Senior react native engineer with ai integration experience

Senior React Native Engineer – AI Integration Experience Required Overview We are looking for a Senior React Native Engineer with production AI integration experience to build an intelligent AI assistant into our existing iOS and Android application. Our application is already live. The user experience and AI chat interface have already been designed. Your responsibility is to build the AI functionality and integrate it seamlessly into our existing React Native application and Laravel backend. This is not a basic chatbot project. We are looking for someone with real experience building production AI applications using the OpenAI API, function/tool calling, and API integrations. Existing Technology Stack React Native Laravel MySQL Firebase AWS iOS Android Project Overview Users should be able to ask questions naturally, such as: "I'm struggling today." "Explain the Fifth Tradition." "Find a meeting tonight." "Find long-term sober living near me." "Find treatment within 20 miles." The assistant should intelligently determine how to answer each request. Sometimes it should respond directly. Sometimes it should search our internal database. Sometimes it should call external APIs. Sometimes it should combine multiple data sources into one response.

Please provide links to AI applications you personally built. Have you implemented OpenAI Function / Tool Calling? Have you integrated AI with existing databases? Describe the architecture you would recommend for this project. Walk us through exactly how your system would process the following request: "Find me a long-term sober living facility within 20 miles." Estimated timeline. Please provide a milestone-based fixed-price estimate. Important We are looking for someone who has built production AI applications, not someone who has only experimented with AI. A video interview is required before hiring. During the interview, you'll be expected to discuss your previous AI projects, explain your proposed architecture for this project, and answer technical questions about your implementation approach. Only applicants willing to participate in a video interview will be considered. This project has the potential to become a long-term relationship as we continue expanding our AI platform. Please begin your proposal with the word Recovery so we know you read the entire posting. Budget will depend on your proposed architecture, experience, and scope. We are looking for the best long-term solution—not necessarily the lowest bid.
