Need a React Native app, SaaS platform, or AI feature that works in production, not just in a demo? I've built them for 30+ startups over 7+ years. Top Rated, $100K+ earned, 57 Upwork jobs. I'm a senior full-stack developer (React, React Native, Next.js, Node.js) who builds AI into products where it saves time, cuts costs, or creates something users will pay for. I own the work end to end, from architecture to launch and support. RESULTS FROM RECENT PROJECTS ✓ Cut manual editorial work by 65% with an AI content pipeline, reducing processing time from 8 hours to under 2 ✓ Built AI-driven automation workflows that run 50,000+ jobs every month ✓ Shipped a production iOS and Android app in 4 weeks, with messaging, subscriptions, and payments ✓ Built a multi-vendor marketplace serving 12,000+ active users ✓ Helped a telehealth platform onboard 3,000+ users in 90 days with secure video consultations and HIPAA-aligned architecture Products I've worked on include Salve Health (telehealth), Clazar (cloud marketplace sales), FlowBuilder (AI workflow automation), and CYA (multi-tenant SaaS for web and mobile). WHAT I CAN BUILD FOR YOU → React Native apps: iOS and Android with Expo, from Figma to the App Store → SaaS platforms: multi-tenant architecture, auth, dashboards, Stripe billing → AI features and agents: chatbots, RAG over your business data, multi-step agents using LangGraph, Claude Agent SDK, and MCP → MVPs: idea to launched product in weeks, built so it doesn't need a rewrite later → Codebase rescue: fixing slow, unstable, or AI-generated "vibe-coded" apps and making them production-ready For AI work, I build in evaluations, guardrails, and cost controls, so it stays accurate and affordable once real users arrive. WHAT CLIENTS SAY "Communicated clearly, asked thoughtful questions... delivered within the agreed timelines."
