Micro Frontend Architecture Enhancement for Scalable Financial Trading Platform

The client aims to enhance their software development process to support scalable growth and improved maintainability of their client-facing web applications. They need to maintain separate, modular applications for core functionalities such as user profiles, trading documents, and account settings, while avoiding technological lock-in and ensuring efficient staffing strategies amidst rapid expansion.

A mid-sized independent financial broker with a broad digital presence, offering trading in stocks, bonds, ETFs, and mutual funds, seeking to modernize and scale its web applications.

• Design and implement a micro frontend architecture to decompose monolithic applications into smaller, manageable modules.
• Develop and integrate at least four distinct micro frontends including user profile management, trading documents, account settings, and notifications.
• Establish a multi-repo development approach to enable independent application updates and deployment.
• Create a custom CI/CD framework to streamline build, testing, and deployment processes across micro frontends.
• Ensure seamless cross-frontend communication, caching, and local environment setup for development and testing.

• Separation of core application functionalities into independently deployable micro frontends (e.g., user profile, documents, settings).
• Application orchestration and integration layer to manage module loading and interactions.
• Custom wrapper or container to facilitate micro frontend loading, communication, and caching.
• Implementation of cross-application communication mechanisms such as Pub/Sub messaging.
• Setup of local and cloud environment configurations to support asset management and seamless development workflows.

• Asset management systems
• Caching mechanisms for application renewal
• Messaging protocols for cross frontend communication (e.g., Pub/Sub)
• CI/CD pipelines for automated build and deployment
• Environment configuration tools for local and production setups

• Support for independent deployment cycles of micro frontends
• High performance with minimized load times across modules
• Scalability to support increasing user base and feature modules
• Security measures for data privacy and secure communication between modules
• Robust caching strategies for application reloads to ensure smooth user experience

The implementation of a micro frontend architecture is anticipated to improve scalability and maintainability of the client’s web applications, reduce deployment times through a custom CI/CD pipeline, and enhance user experience. The project aims to support rapid onboarding of new features, thereby enabling the client to handle thousands of new accounts annually and manage assets exceeding $20 billion more efficiently.
