About this gig
FlutterFlow & Flutter App Development Fintech, Custom Apps & MVPs Built to Launch
Got an app idea and no idea where to start turning it into something real? That's exactly where I come in.
I'm a FlutterFlow and Flutter developer who builds fast, functional, cross-platform apps for founders and startups with a particular focus on fintech and finance-adjacent apps, where clean UX and airtight functionality actually matter more than flashy design. Whether you're building a budgeting app, a digital wallet, a custom marketplace, a chat platform, or something nobody's built quite like yours yet I take it from idea to a real, working app on iOS and Android.
What I build:
- Custom mobile apps fintech, marketplace, social, chat, and beyond
- Secure user authentication
- Backend integration with Firebase and third-party APIs
- Admin panels for managing your app after launch
- Full FlutterFlow builds frontend and backend, done right the first time
- Native Flutter development when your app needs more than FlutterFlow alone can offer
If you've got an idea sitting in your notes app right now, let's talk about what it actually takes to build it. Message me and tell me what you're trying to create.

My name is Franklin, I help businesses turn ideas into working websites and mobile apps from a first landing page to a full cross-platform app your customers actually use. I build with WordPress for fast, scalable websites, and Flutter / FlutterFlow for native-feeling iOS and Android apps, backed by clean APIs and real backend logic — not just a pretty frontend.
Whether you need a business website that converts, an MVP to show investors, or a full app rebuild, I focus on shipping something that works reliably, on time, and built to grow with you.
FAQ
Have you built a fintech app before, or is this more about the skills fintech apps need?
I bring the core pieces fintech apps rely on — secure authentication, clean transaction flows, and solid backend integration. If your app has specialized needs like KYC/compliance, let's talk specifics upfront so I can tell you honestly what I can handle directly and what might need a specialist alo
FlutterFlow or native Flutter — which one do I need?
FlutterFlow gets you a working app faster and is great for MVPs and most custom apps. If your app needs deep custom logic, heavy performance optimization, or something FlutterFlow's visual builder can't handle cleanly, I'll build in native Flutter instead. I'll tell you which one your idea actually
Can you connect my app to Firebase or another backend?
Yes — Firebase is my default, but I also integrate third-party APIs and other backends depending on what your app needs.
I only have an idea, no wireframes or design — can you still help?
Yes. Tell me what you're picturing and I'll help shape it into a real, buildable structure before we start development, so you're not paying to figure things out mid-build.
How long does a build take?
Depends on scope — a simple custom app can be 5-7 days, something with chat, auth, and backend integration is usually 2-3 weeks. I'll give you a real timeline once I know what you're building, not a generic estimate.
