The firm needed a high-performance application with multiwindow communication for managing orders between traders. Its existing Electron-based approach complicated testing and development, necessitating a more streamlined architecture.
Solution
Modern Browser Architecture
Toptal replaced the Electron-based approach with a browser-based solution using native browser APIs for multiwindow communication, simplifying testing and enabling shared application state with minimal additional code.
Reusable, High-performance Components
Toptal refactored the React front end into reusable components, optimized performance by reducing unnecessary rerenders and moving computationally intensive logic to web workers, and helped define API structures.
Outcome
Fastest-moving Project
The application remained on track and became the firm’s fastest-moving development project while other initiatives experienced delays. Early demonstrations also delivered substantially more functionality than clients expected.
Stable, Optimized Application
Toptal provided a stable version of the application with its planned functionality working correctly and optimized for performance, while reusable components developed for the application were adopted across other projects.
