I want to build my own digital wallet app.

I'm currently researching companies that have experience in fintech and digital wallet app development. My goal is to build a secure, scalable, and user-friendly wallet with features like:

Secure user authentication
Bank account & card integration
QR code payments
P2P money transfers
Transaction history
Rewards & cashback
Bill payments
Multi-currency support (optional)
Strong security and compliance

So far, I've come across these companies during my research:

Tata Consultancy Services (TCS)
Cognizant
HCLTech
Techanic Infotech
IBM
Deloitte
Netguru

If you've worked with any of these companies or have experience building a digital wallet app, I'd love to hear your recommendations. Which company would you suggest based on quality, communication, and overall development experience?

Looking forward to your suggestions. Thanks!
