React Native & Full-Stack JS Developer | AI Web Apps & SaaS

8+ years building production-ready mobile apps, AI SaaS platforms, and full-stack web products. 30+ live mobile apps shipped | 25+ web apps deployed | 80 projects completed on Upwork | 6,844+ hours | $290K+ earned | 100% Job Success | Top Rated Plus 📱 CROSS-PLATFORM MOBILE APPS React Native apps for iOS and Android from a single codebase, native modules where needed (camera, Bluetooth, push notifications), real-time API-integrated features, App Store and Play Store deployment. Live right now: DRFT (travel social, runs on Apple Vision Pro), Ask Filos (bilingual Arabic/English AI legal copilot), Referee (two-sided marketplace, v1.8 to v10.1 across two years of releases), KUSA (community app scaled to 14 cities), BrainFlow (personalized affirmation-video generation). 🤖 AI SAAS PLATFORMS & OPENAI INTEGRATIONS Multi-tenant SaaS products with LLM-powered features: AI chat interfaces with streaming responses and rate-limit handling, AI-powered dashboards that summarize and surface data, automated workflows that connect model outputs to real business logic, and usage-based or subscription billing tied to Stripe. Shipped: Vidsembly (AI video-creation SaaS: full media-automation pipeline, token system, credit + subscription billing), Novelyst (AI novel-writing SaaS: narrative-consistency engine, token metering, dual billing); plus the production AI inside Ask Filos and BrainFlow above. 🚀 STARTUP MVPs For early-stage founders, I move from idea to a production-ready MVP fast, a lean data model, working auth (email/OAuth), the core user flows, and payments wired in from day one. Built to extend after you raise, not thrown away and rebuilt. Recent: MusicKids (admissions & management web app for music schools; enrollment, student records, and operations in one place) and BestBosses (awards platform on Next.js/Nest with public site + nomination and moderation flows) both taken from idea to live. 🌐 FULL-STACK WEB APPLICATIONS SaaS dashboards, admin panels, and marketplace platforms on Next.js and Node.js, backed by PostgreSQL or Supabase. Live right now: CertifyOS (healthcare provider-data platform on React/Next.js/Node/AWS, serving major US health plans), EmpireOS (AI revenue platform; the site itself is a working product simulation), Marqly (AI bookmark manager rated 4.9★ with 200k+ users on the Chrome Web Store, plus its iOS app). I pay close attention to schema design, API structure, and query performance so the app holds up once real usage hits it, not just at demo scale. 💳 API & PAYMENT INTEGRATIONS Stripe subscription billing (proration, dunning, webhook idempotency), RevenueCat and in-app purchases on mobile, REST API integration, and authentication: OAuth, JWT, session-based. In production; BXR London (member app for a members-only London boxing gym; Mindbody integration, Apple Pay, Apple Wallet, 2FA), Referee's automated Plaid payouts, and subscription billing across the SaaS builds above Every project above is in my Portfolio section below with live links, or search any of them by name on the Browser/App/Play Store. My work is verifiable, not claimed. 🛠️ TECH STACK Mobile: React Native (Expo & CLI), iOS & Android Frontend: React.js, Next.js, TypeScript, Tailwind CSS Backend: Node.js, Express.js, PostgreSQL, Supabase, MongoDB AI & Integrations: OpenAI API, Claude, Stripe, RevenueCat, REST APIs, OAuth, Firebase 🤝 HOW I WORK Discovery first: I scope the data model and architecture decisions before writing code, not mid-build, so we're not rebuilding foundations two weeks in. Iterative delivery: visible milestones along the way, not a single black-box release at the end. Clear communication: async updates by default, calls when they're actually useful. The words clients use most in my reviews: collaborative, reliable, committed to quality. Long-term by default: the developer who ships your v1 maintains your v3. My flagship apps have 20–25+ releases with me across years. If you need a mobile app shipped to the stores, an AI SaaS platform, or a full-stack build done right the first time, send me your project details and I'll tell you exactly how I'd approach it. ✅
