Have an innovative app idea, a prototype, or a business platform you want to bring to life? Whether you're starting with a simple concept or already experimenting with tools like Lovable, Bubble, Replit, or n8n, I can help turn your vision into something your customers will love to use. I help founders and businesses turn ideas into AI-powered products, internal tools, and scalable software, without wasting months or tens of thousands of dollars. Client results: • $350M+ raised by clients • 2M+ users on apps I designed and developed • 10K+ five-star reviews across apps built • Top 1% in App Design & Development on Upwork A few years ago, I was sitting exactly where many of my clients are today: trying to turn an idea into an app. I was looking for freelancers, tried to build it myself and hired the wrong teams. It was a nightmare to say the least. After years of mistakes and learning to code, I finally launched SchooLinks, which grew into an Inc. 5000 company and raised over $90 million. Since then, I've helped more than 150 founders launch products across SaaS, marketplaces, AI tools, mobile apps, and internal platforms... some of which have made it to Forbes. Book your consultation today! I’ll save you months of frustration by helping you understand the ins and outs of bringing an app / platform to life: How much it costs, how long it takes, what’s the process and more. The apps I’ve built come in the form of: SaaS platforms, internal platforms, Mobile & web apps, Marketplace apps. Trusted By: Harvard, Samsung, Indeed, Yamaha, University of South Florida, and more. Technologies: OpenAI, Claude, Gemini, Flutter, Node.js, Angular, AWS, MongoDB, Figma If you’re serious about building your app the right way, let’s talk!

Right now, most SaaS founders and businesses are losing users and revenue because their apps are not optimized for mobile, their App Store submissions get rejected, their Stripe or Supabase setup breaks on mobile, or their AI-powered systems are not working as expected. That’s where I come in. I help you convert, build, fix, and scale high-performance mobile apps and AI SaaS systems using Claude Code, React Native Expo, and vibe coding tools without trial and error. ⚠️ If You’re Experiencing Any of These: ❌ Your web app needs to be converted to iOS & Android ❌ Apple keeps rejecting your app or it behaves like a webview ❌ Stripe payments or Supabase auth not working on mobile ❌ Your Lovable, Replit, or Base44 app is broken or incomplete ❌ Your AI SaaS or automation system not performing ❌ Push notifications, offline mode, or native features missing 👉 You’re losing users, retention, and revenue every single day. ✅ 𝐖𝐡𝐚𝐭 𝐈 𝐃𝐨 (𝐀𝐧𝐝 𝐃𝐨 𝐁𝐞𝐭𝐭𝐞𝐫 𝐓𝐡𝐚𝐧 𝐌𝐨𝐬𝐭): 🔥 Web App to Mobile App Conversion Done Right No weak webviews. I convert your web app into a real mobile app using React Native, Capacitor, or Expo with native performance and smooth UX. 🔥 AI SaaS & MVP Development That Actually Works I build scalable AI SaaS apps and MVP platforms using Claude Code, OpenClaw, Gemini, and modern stacks designed for real-world usage and growth. 🔥 Vibe Coding & AI App Development From Lovable, Replit, and Base44 apps to full AI-powered systems, I fix, rebuild, and optimize apps using advanced AI assisted development tools. 🔥 Mobile App Deployment & Store Approval I handle App Store and Google Play submission, fixing rejection issues, optimizing performance, and ensuring your app gets approved and live. 🔥 OpenClaw Automation & Backend Systems I build smart automation workflows, API integrations, and backend systems that reduce manual work to your business operations. 💰 𝐖𝐡𝐚𝐭 𝐘𝐨𝐮 𝐆𝐞𝐭: ✔️ High-performance mobile apps (iOS & Android) ✔️ Faster App Store approval & successful deployment ✔️ Working Stripe, Supabase, and backend integrations ✔️ AI-powered SaaS systems that scale with your business ✔️ Clean UI/UX with smooth performance and real native experience ✔️ Less manual work 🧠 𝐖𝐡𝐲 𝐇𝐢𝐫𝐞 𝐌𝐞? Most developers: ❌ Build slow webview apps ❌ Break features during conversion ❌ Don’t understand deployment or AI systems I don’t. I understand both: ✔️ Mobile app architecture (what gets approved & performs well) ✔️ AI SaaS systems & automation (what actually works in production) That combination is why my clients don’t come back saying 👉 “It’s not working.” ⚡ Let’s Be Direct: If your app is not optimized for mobile, not deployed properly, or your AI system is not working… You are already losing users, growth, and revenue every single day. 📩 Next Step: Send me a message or invite me to your job. I’ll quickly review your project and tell you: ✔️ What’s wrong ✔️ What’s missing ✔️ How to fix it fast No fluff. Just results.
