Performance, Security, and Scalability Issues with Existing Mobile App

NDS's existing iOS-based mobile application, serving a large and growing user base (115,000+ daily users), is built on an outdated technology stack. This results in slow performance, frequent crashes (up to 95% crash rate), and significant security vulnerabilities, hindering the ability to update to the latest iOS version and impacting user experience and compliance with regulations like GDPR, SOC 2, and ISO 27001. Large document downloads (1,500 files) often time out.

About the Client

NDS provides a web platform and mobile app for managing corporate documentation, serving businesses with a focus on secure and compliant document handling.

Project Objectives

Migrate the mobile application to a modern, scalable, and maintainable technology stack (Swift).
Improve application performance and reduce crash rates to a minimum (target: 99.5%).
Enhance application security to meet and exceed industry compliance standards (GDPR, SOC 2, ISO 27001).
Enable seamless and reliable download of large document volumes.
Improve the development team's velocity by adopting modern development practices.

Functional Requirements

Secure document access and management.
Offline access to documents (where applicable).
Efficient document search and filtering.
Real-time collaboration features (editing, commenting).
Secure document sharing capabilities.
Reliable large file download functionality.
User authentication and authorization.

Preferred Technologies

Swift

Azure DevOps

SQLite

Firebase Crashlytics

SFHFKeychainUtils

SecureNSUserDefaults

Querer

Integrations Required

Azure DevOps (for CI/CD)
Potentially integration with existing authentication/authorization systems

Key Non-Functional Requirements

High Availability
Scalability (to support increasing user base and document volume)
Security (Data encryption, vulnerability mitigation)
Performance (Fast response times, efficient resource utilization)
Zero Downtime Deployment
Maintainability (Easy to update and maintain)

Expected Business Impact

This project will result in a more reliable, secure, and scalable mobile application, leading to improved user satisfaction, reduced operational costs (due to fewer crashes and easier maintenance), enhanced compliance posture, and the ability to support future growth. The modernization will also allow for easier adoption of new iOS features and security updates.
