Secure Backend & Payment Integration
3-4 Weeks
iOS, Android, Python Backend
Processing financial transactions natively in mobile applications requires strict PCI compliance and the isolation of client secrets away from the compiled application.
We engineered a highly secure payment pipeline that isolates sensitive cryptographic keys on a Python Flask server while delivering a frictionless native checkout experience via Flutter.
Architected a server-side ClientSecret isolation pipeline to prevent reverse-engineering vulnerabilities.
Integrated the flutter_stripe SDK to handle secure, native UI rendering for card inputs.
Engineered dynamic currency conversion logic converting front-end values to Stripe-compliant integer formats.
Established a 100% secure, PCI-compliant transaction flow.
Eliminated client-side vulnerability of sensitive API keys.
Streamlined the checkout experience, reducing user friction during payment processing.
