Muhammad Owais A.

AI app developer and React Native engineer — I build mobile and web apps with real AI inside them: LLM chat assistants, RAG over your own data, and AI agents that take actions, shipped to the App Store, Google Play and the web. Top Rated, 24 completed contracts, 10+ apps live, 5+ years in production. Clients usually come to me in one of three situations: they want to add AI (ChatGPT-style assistants, document Q&A, automation) to a product they already have; they have an idea and need it taken from first screen to App Store and Google Play; or they have a half-built React Native / Next.js app someone else couldn't finish. All three end the same way — shipped. AI ENGINEERING & LLM INTEGRATION ✦ LLM integration — OpenAI (GPT), Anthropic Claude and Google Gemini APIs inside mobile and web apps ✦ RAG (Retrieval-Augmented Generation) — chat with your PDFs, docs, knowledge base or database using embeddings and vector search (pgvector, Supabase, Pinecone) ✦ AI agents & tool calling — assistants that book, search, update records and call your APIs, built with LangChain / function calling ✦ AI chatbots & customer-support bots — streaming responses, conversation memory, guardrails, human hand-off ✦ Voice & vision AI — speech-to-text, text-to-speech, image understanding and generation in React Native apps ✦ Prompt engineering, cost control and evaluation — so your AI features are accurate, fast and affordable in production ✦ AI MVPs and AI SaaS — from prototype to a paid, subscription-ready product MOBILE APP DEVELOPMENT ✦ React Native + Expo apps for iOS and Android — architecture, UI, backend, store launch ✦ Payments & subscriptions — Stripe, in-app purchases, RevenueCat, flows that pass store review ✦ Real-time — chat, WebSockets, Agora video & audio calls, live sync ✦ Push notifications, deep links, EAS builds and OTA updates ✦ Rescue & rewrite — taking over stalled React Native codebases and getting them live WEB & FULL-STACK ✦ React and Next.js web apps — SaaS platforms, AI dashboards, customer portals, admin panels ✦ Node.js / Express APIs, serverless functions, Supabase / PostgreSQL backends ✦ Figma to React with TypeScript and Tailwind CSS ✦ Auth, Stripe, third-party API integrations, deployment on Vercel, AWS or DigitalOcean Mobile app, web app, API and AI layer from one developer — one point of contact, one person accountable.
