Hi Client,
For developing a comprehensive e-SIM platform compatible with web, Android, and iOS, I propose using a modern tech stack like React.js for the web frontend, Flutter for cross-platform mobile app development, and Node.js with Express for a robust and scalable backend. These technologies will ensure seamless API integration, secure user account management, and efficient payment processing.
In a recent project, I built a cross-platform digital subscription platform with similar requirements. I implemented secure user authentication using OAuth 2.0, integrated third-party APIs for real-time data exchange, and designed an intuitive user interface that enhanced navigation and usability. For payment processing, I integrated Stripe and PayPal, ensuring compliance with PCI-DSS standards while offering multiple payment options to users.
Additionally, I focused on implementing responsive designs and error-handling mechanisms to provide a flawless user experience across all devices. My approach to modular development ensured that the platform was scalable, secure, and easy to maintain.
If selected, I’ll bring a dedication to delivering high-quality code, effective communication, and creative problem-solving to bring your vision to life. I look forward to collaborating on this innovative project.
Best regards,
