📱 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

🤝 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. ✅
