I build AI-powered iOS and Android apps and the backend behind them. On the app side I work in Swift, SwiftUI, Kotlin, Jetpack Compose and Flutter. On the AI side I integrate LLMs like OpenAI, Claude and Gemini, build RAG and AI agents, and run ML models on device with Core ML and ONNX. In 8 years I have shipped more than 100 apps to the App Store and Google Play, several with over 1 million downloads, and I hold Top Rated Plus status here on Upwork. Clients usually come to me with one of two goals: add a useful AI feature to an app that already has users, or take a new AI product from idea to the stores with a backend that can grow with it. 𝗔𝗜 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗜 𝗯𝘂𝗶𝗹𝗱 • AI chat assistants and copilots inside mobile apps, with streaming replies, memory and tool calling • RAG over your documents, knowledge base or product data using vector search • AI agents that take real actions through your APIs, including MCP integrations • Voice features: speech to text, text to speech and realtime voice assistants • On-device AI with Core ML, Apple Foundation Models, ONNX Runtime, ML Kit and TensorFlow Lite for private, offline features • Image and document AI: OCR, classification, generation and smart editing 𝗠𝗼𝗯𝗶𝗹𝗲 𝗮𝗻𝗱 𝗳𝘂𝗹𝗹 𝘀𝘁𝗮𝗰𝗸 • Native iOS: Swift, SwiftUI, Objective-C, watchOS, widgets • Native Android: Kotlin, Java, Jetpack Compose • Cross platform: Flutter and React Native • Backend: Supabase, Firebase, PostgreSQL, REST APIs, webhooks and admin dashboards • Subscriptions and in-app purchases, BLE and device integrations, maps and real-time sync • App Store and Google Play release, review rejections and long-term maintenance 𝗦𝗲𝗹𝗲𝗰𝘁𝗲𝗱 𝘄𝗼𝗿𝗸 • SKAI Weather, storm and hurricane tracker with over 1M downloads • WallPics, live wallpaper app on iOS and Android with over 1M downloads • eCebuana, fintech app with secure money transfer flows • Mind Mate AI and ChatCore AI, AI assistant apps built on LLM APIs • iOS work for a Y Combinator backed AI startup • BLE voice control app for iOS and Android, and a healthcare app for field clinicians 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I start with the business goal, then suggest the simplest architecture that will hold up in production. You get working builds early, short written updates, and a straight answer when something isn't worth building. AI features are designed with cost, speed and privacy in mind, so the model and setup fit your budget and your users. If you want to add AI to an existing app or build a new AI product for mobile and web, send me a short note about it and I'll reply with a practical plan and timeline.
