React Native Engineer | AI-Powered iOS & Android Apps | Expo, Next.js

100% Job Success and a 5.0 rating across 5 clients. In the last year I billed around 750 hours, and most of that was two contracts: about 400 hours on one and 350 on the other, each with a single client. People who hire me tend to keep me. I build React Native apps for iOS and Android, and I build the AI features that go inside them. Most of my work lately has been mobile. Expo, EAS builds, store submissions, the whole path from repo to App Store. That last stretch is where a lot of mobile projects stall, and usually it isn't the code. It's provisioning profiles, review rejections, and nobody wanting to own that part. About AI, since everyone asks. I use it daily and I'll build LLM features into your app: chat, transcription, real-time analysis, agents. What I'm actually useful for is the boring production side. What your app does when the model returns malformed JSON at 2am. What it costs per user once you have 10,000 of them. Which features shouldn't touch a model at all, because a database query does the same thing faster and cheaper. What I work on: React Native and Expo apps. One codebase, both platforms. For a small team that's often the difference between shipping and not shipping. LLM features inside mobile apps. OpenAI and Anthropic APIs, streaming, cost control, sane fallbacks for when the model doesn't cooperate. Next.js on the web, when your app needs an admin panel or a dashboard. Automation with n8n to connect all of it to your CRM or your database. Someone on your team is probably doing two hours of manual data entry every morning and nobody has priced what that costs per year. MVPs, scoped down to what actually tests the idea. How I work: I ask questions before I write code. If a feature is going to take three weeks and return nothing, you'll hear that from me before you pay for it. And you'll hear about delays from me first, not from a deadline that quietly passed. What I'm working on now: a React Native app that runs AI analysis on user data. It's under NDA so I can't name it, but I've been on it since May and it's the kind of work I want more of. Before that, a multi-tenant SaaS platform on Next.js and Supabase, four months with one client. That one's in my portfolio. Stack: React Native, Expo, TypeScript, React, Next.js, Node.js, NestJS, Supabase, Firebase, OpenAI and Anthropic APIs, n8n, Figma. Tell me what you're building and where it's stuck. I'll get back to you within 24 hours either way, including if I think I'm not the right fit.
