Zaid M.

I build and ship production mobile and web apps with AI built in: React Native and Expo on iOS and Android, Next.js on the web, Supabase/Postgres backends, and LLM features with OpenAI, Claude, and Gemini. Recent work: Scavenger, a 152M-product AI platform I migrated off Lovable onto Supabase and Vercel, now serving 15,000+ users and over $500K/month.

7+ years in full-stack JavaScript/TypeScript and React Native. I take products from idea to the App Store, Play Store, and production web, covering design, backend, payments, and AI.

What I build

AI-powered apps: LLM features with OpenAI, Claude, and Gemini. Chatbots and support agents, RAG over your own data (pgvector and vector databases), AI agents and workflow automation with n8n, voice AI with Retell and Vapi, content and image generation, and document/NLP pipelines. I develop AI-assisted with Claude Code and Cursor, which means faster delivery.

Mobile apps: Cross-platform iOS and Android with React Native and Expo. Offline-first sync, push notifications, in-app purchases, payment integrations, real-time features, and full App Store and Play Store publishing. Example: Tequal, an Expo and Supabase wellness app that works fully offline and syncs when back online, live on both stores.

Web apps and SaaS: React and Next.js with Node.js. Multi-tenant SaaS, admin dashboards, Supabase and Postgres with row-level security (RLS) and auth, Stripe subscriptions and Stripe Connect, SSR/SSG, SEO, and PWAs. Example: Codify HRMS, a multi-tenant HR platform with role-based access.

Independent, not an agency. You work directly with me from wireframes to deployment, with clear communication, honest timelines, and maintainable code. Based in Istanbul (UTC+3), available full-time, and I overlap your working hours.
