If you need a React Native developer who ships reliable iOS and Android apps, not just code, you're in the right place. 🎯 I'm a senior React Native and Expo developer with 10+ years of production experience. I'm part of Toptal's vetted network (top ~3%) and the founder of Inseed, a boutique mobile development studio on Upwork. Together, we've delivered mobile and AI-powered products for companies like Carrier, National Debt Relief, Roblox, Hazel (.co), Bookvid, and YuMe, from early-stage startups to Fortune 500 teams. 🏆 My core focus is React Native and Expo, building iOS and Android apps that go through App Store and Play Store review, hold up under real user load, and stay maintainable as your product grows. I also build AI-powered features (OpenAI, LangChain, Pinecone) and React/Next.js web apps for clients who want one consistent engineering partner across platforms. 🚀 What I bring to your project: - 10+ years building real-world production software - 6+ years of React Native (Expo + bare workflow, App Store & Play Store releases) - Deep AI integration: OpenAI API, LangChain, Pinecone, vector search - TypeScript-first development with clean architecture and long-term maintainability - Testing discipline: unit, integration, and E2E (Jest, Detox, Cypress) - CI/CD pipelines, crash monitoring, analytics, and performance optimization - Clear communication, early escalation, and full ownership of delivery 🛠 Tech I work with daily: React Native · Expo · TypeScript · React · Next.js Node.js · GraphQL · REST APIs OpenAI API · LangChain · Pinecone Firebase · Supabase · AWS · Docker · Vercel 📈 Real examples of impact: - Stabilized and scaled a React Native app serving thousands of monthly users, refactored core modules, reduced crashes, and improved release confidence. - Led architecture and delivery of enterprise mobile products at Carrier Digital, integrating Salesforce APIs via AWS Lambda inside a large Mono Repo team. - Built AI-powered chat, recommendation, and workflow features using OpenAI + vector search, improving engagement and cutting manual work for end users. - Reduced technical debt in legacy React Native codebases while maintaining feature delivery velocity, without slowing down the roadmap. 💬 How I work: I care about your product outcome, not just closing tickets. I write clean, structured TypeScript, communicate proactively, and flag issues early. If it's on my plate, it gets delivered. If you're building a React Native or Expo app, or need AI features integrated into an existing mobile product, I'd love to hear about it. Feel free to send a message; I respond within a few hours. 📩
