Hamza Z.

Full stack SaaS and AI developer. I build the platforms that handle real users, real payments and real scale, then wire in AI that actually works in production. 8+ years full stack. 50+ projects on Upwork, $300K+ earned, 100% Job Success and Top Rated Plus. What I build for clients: . Multi tenant SaaS with subscription billing and strict tenant isolation . AI features that ship: Claude and OpenAI integration, RAG, chat, agents, document and data extraction . Stripe and Stripe Connect: subscriptions, usage billing, payouts, secure webhooks . AI native ecommerce platforms in the Shopify class . Fintech and healthcare portals with sensitive data and role based access . B2B dashboards, admin panels, CRMs and internal tools . Taking AI built or half finished MVPs (Lovable, Cursor, Replit) to real production Tech I work with daily: . React, Next.js, Vue, Nuxt, TypeScript, TailwindCSS . Node.js, Laravel, PostgreSQL, MySQL, Supabase, Redis . Claude and OpenAI APIs, RAG, AI agents, MCP . AWS, CI/CD, multi tenant architecture, deployment and scaling I build with AI coding tools like Claude Code and Cursor daily, fast, but I review every line, because AI speed without engineering judgment ships bugs. I set up CI/CD and handle deployment, scaling and infrastructure, so you never think about devops. I focus on understanding your business first, not just the ticket. Clean architecture, clear communication, no fluff. Have a project in mind? Send me a message or invite me to your job and let's jump on a quick 5-minute call to talk through it. I reply fast. Bring me the idea. I'll bring the engineering to make it real.
