I am a AI Powered Website Designer and Developer. Daily I am using Claude, Cursor, and Lovable or you can call Vibe Coding or Vibe Builder. Most businesses get locked into whatever platform their last developer happened to know — and then get stuck when they outgrow it, or need something a template can't do. I work across the stack, so you get the right build for what you actually need, not whatever I happen to specialize in. I design and develop on GHL funnel and a websites, WordPress, Shopify, Squarespace, and Showit for CMS-driven and e-commerce sites, and build custom frontends with Next.js and React when a project needs more than a page builder can deliver. I also handle the parts most developers treat as an afterthought: domain setup, DNS configuration, and clean platform-to-platform migrations that don't break your SEO or lose your data in the process. I build with AI-assisted tools — Cursor, Claude, ChatGPT, and Lovable — as part of my actual workflow, not a gimmick, which means faster turnaround and lower cost without cutting corners on quality or code you can't maintain later. Beyond general web development, I've built specific depth in a few verticals: real estate (IDX/MLS-integrated, lead-capture-focused sites for agents and brokerages) and photography/videography (fast-loading, booking-focused portfolio sites). If your business falls into one of these, I likely already know the integrations, tools, and conversion patterns that matter for it — happy to share relevant examples. I've spent 9+ years building websites (200+ projects across 25+ countries), and you work directly with me — no hand-offs to junior staff or offshore teams. Pricing is transparent and upfront, with post-launch support included as standard. If you need a website built, migrated, or rebuilt — on the platform that's actually right for your business — let's talk. Connect with me if required a website designer or developer: - Website Development on various platforms WordPress, Squarespace, Shopify, NextJs ReactJs - Landing Pages Development and Marketing Forms Hubspot, Mailchimp - Funnels and Vibe Builder based websites design on GHL or Clickfunnels - Domain migration and Configuration, DNS Setup - Website migration from one platform to another

If you built a mobile app prototype with Bolt, Lovable, Cursor, or Replit and it isn't ready for real users, or you have an idea and need someone to turn it into a real, working app, this is what I do. My name is Bilal Mustafa I've been building React Native apps for seven years, with 100+ shipped to the App Store and Play Store. The Projects I Take On Fixing an AI-Generated App: AI tools are good at getting you 80% of the way to a working app fast. The last 20%, the part that decides whether Apple and Google actually approve it, whether it runs smoothly on a real phone, whether it handles a dropped connection or a background push notification correctly, is usually missing. I go through the existing code, tell you honestly what's solid and what needs to be rebuilt, and get it to a state that passes review and holds up for real users. Building a New Idea into a Real MVP: If you're starting from an idea rather than a prototype, I help you shape it into something buildable first: a clear, honest scope, not a wishlist. Then I build it in stages, so you have something real to test early instead of waiting months for a finished product. What You Get Either way, here is the standard for every project: App Store & Google Play Approval: Your app will pass review. I've submitted 100+ apps across both stores, so I know what triggers a rejection before it happens. Rigorous QA Testing: Your app will be tested on real devices, not just a simulator. A QA engineer checks every build before you see it, and you get a test document showing exactly what was checked. Clean Code: Your code will be clean enough for someone else to pick up later. Whether that's your own future hire or another contractor, the codebase won't be a mystery. My Tech Stack Mobile: React Native, Expo, TypeScript Backend: Node.js, Firebase Payments: Stripe, RevenueCat AI & Machine Learning: OpenAI API and on-device ML Kit (when a project needs real AI features, not AI just for its own sake). The Guarantee Every project comes with 60 days of free bug fixes after launch. Let's Talk If you want an honest read on what you have, whether it's a prototype that needs fixing or just an idea, send me a message. I'll tell you plainly what it would take and roughly how long. There is no charge for that conversation. Bilal Mustafa Code Gradients
