I'm Ezekiel, founder of OJX Studios. I build mobile & web apps (React Native, Flutter), fix and deploy AI-built apps (Lovable, Bolt.new), and design websites (WordPress, Wix, Shopify). From MVP to production-ready product, I write clean code, communicate clearly, and deliver on time. Let's turn your idea into a working, scalable product.
FAQ
Which platform is best for my app idea?
It depends on your goal. Flutter suits complex custom apps, FlutterFlow and Adalo are great for fast mobile MVPs, Bubble handles web-based SaaS and marketplaces, and Glide works best for data-driven apps. Message me your idea and I'll recommend the right fit.
Can you add AI features like ChatGPT or Gemini to my app?
Yes. I integrate GPT-4o, Gemini, and other AI APIs directly into your app — whether it's a chatbot, smart search, recommendation engine, or generative tool.
Can you fix an app that someone else already built?
Absolutely. Share access to your project before ordering and I'll review it within 24 hours, then give you a clear scope and quote at no charge.
Do I get full ownership of the app after delivery?
Yes. You receive complete source files, full platform access, and 100% ownership of everything delivered upon final payment. No strings attached.
