I will build AI mobile apps, fix AI features, and integrate OpenAI or fine-tuned models

About this Gig

Need an AI-powered mobile app, chatbot feature, OpenAI integration, or help fixing an existing AI app? I’m a Senior AI App Engineer with 6+ years of production experience in Swift, SwiftUI, Java, Kotlin, Android, UIKit, Firebase, REST APIs, CoreML, and LLM integrations. I help founders and businesses build reliable AI apps that are ready for real users — not just quick prototypes. I can help you with: AI iOS app development using SwiftUI or UIKit OpenAI / ChatGPT API integration AI chatbot or assistant inside your mobile app Streaming AI responses like ChatGPT RAG-based assistant using your business data or documents Fine-tuning workflow support and dataset preparation Fixing broken AI features, API errors, crashes, or poor responses Firebase / Firestore / Supabase integration Login, subscriptions, in-app purchases, and App Store-ready flows Performance, memory, and architecture improvements For fine-tuning, I can help you decide whether your use case actually needs fine-tuning or whether RAG, better prompts, structured outputs, or better app logic will solve it faster and cheaper. Fine-tuning is best when you need consistent tone, domain-specific behavior, or outputs that prompt engineering alone cannot reliably achieve. My goal is simple: build or fix your AI app in a clean, scalable, and production-ready way.

Requirements

To get started, please share: A short description of your app idea or the AI feature you want to build/fix. Your current app status: new app, existing app, MVP, or live App Store app. Your tech stack, if known: Swift, SwiftUI, UIKit, Flutter, React Native, Firebase, Supabase, etc. The AI provider you want to use: OpenAI, Claude, Gemini, Llama, or “not sure yet.” Any designs, Figma file, screenshots, wireframes, or reference apps. For bug fixing: screenshots, screen recording, crash logs, API errors, or steps to reproduce the issue. For RAG/fine-tuning: sample data, documents, FAQs, chat history, or examples of ideal AI responses. Your expected timeline and main goal: MVP, App Store release, bug fix, better AI responses, or performance improvement. Access needed for the work, such as GitHub repo, Firebase project, API keys, TestFlight, or backend documentation. Note: Please do not share sensitive production keys directly in chat. Use a safe method or create temporary/restricted access where possible.
