Katherine
About this gig
Got an app idea but no time or no dev team to build it? I'm a Base44 developer who turns founder ideas into working AI apps and SaaS MVPs, fast.
I build on Base44 with Claude Code as my engine, so you get modern, production-ready software in days, not months. Whether it's an AI SaaS, internal tool, CRM, dashboard, client portal, admin panel, or business automation, I turn your idea into a real, launchable product.
Every build includes:
- Clean, responsive UI
- Solid database design (Supabase)
- User authentication
- API integration with the tools you use
- React / Next.js where it fits
- A scalable structure that grows with you
From a simple custom AI app to a full SaaS MVP with AI automation, I focus on shipping something that actually works not a half-finished prototype.
You get a developer who thinks like a founder: clear communication, fast delivery, and an app you can demo or launch immediately.
Message me before ordering so I can scope your Base44 app and recommend the right package. Let's launch your AI startup in days.

FAQ
What is Base44 and why should I build my app with it?
Base44 is an AI platform for building custom apps, dashboards, and SaaS products fast, without heavy traditional coding. It lets founders launch a real, scalable product in days instead of months which means lower cost and a working app you can put in front of users or investors right away.
I have an idea but no clear spec can you still build it?
Absolutely. You don't need a technical document or wireframes. Message me with what you want the app to do and who it's for, and I'll help shape it into a clear build plan and recommend the right package.
Can you connect APIs, databases, and payments?
Yes. I handle API integration, database design with Supabase, user authentication, and Stripe or other payment flows, so your app is fully functional and ready to launch not just a front-end shell.
Do you build with React and Next.js, or only no-code?
Both. I build on Base44 and extend with React and Next.js where your app needs custom functionality or room to scale, so you're never boxed in by the platform's limits. (Catches "React" + "Next.js"; reassures the more technical buyer that they won't hit a wall.)
What happens after delivery do you provide revisions and support?
Every package includes revisions, and I make sure your app is stable and working before we close the order. If something needs adjusting after launch, message me — I'm here to keep your product running, not disappear after delivery.
