About this gig

Hello, welcome to my profile! I'm Nunes, a professional full-stack FinTech app developer. I specialize in building secure and scalable financial apps that make managing money simple and convenient.

I develop digital wallet apps, bill payment platforms, and merchant payment solutions tailored to your business needs. Your app can handle wallet funding, peer-to-peer transfers, merchant payments, and automated bill payments for airtime, data, electricity, and TV subscriptions. For merchants, I integrate features like QR payments, POS/softPOS systems, settlement tracking, and detailed transaction reporting.

I focus on creating apps that are reliable, secure, and user-friendly, with clean designs, robust backends, admin dashboards, and KYC/AML compliance. Whether you're launching a new FinTech product or scaling an existing one, I provide end-to-end development ready for real-world use.
