Challenge

The existing application was built on a tightly connected architecture that made even minor changes difficult to implement. Updates required full-system deployments, creating bottlenecks that slowed development, limited scalability, and made it harder to respond to changing business requirements.

Solution

Modular Front-end Architecture

Toptal engineers rebuilt the front end using React, TypeScript, and Module Federation, introducing a micro front-end architecture that allowed teams to develop and deploy application features independently.

Independent Back-end Services

The development team transitioned the back end to a microservices architecture using Node.js and .NET, separating business functions into individual services that could be developed, tested, and scaled independently.

Outcome

Faster Software Releases

Independent feature deployments eliminated the need for coordinated, full-system releases, accelerating development cycles and reducing the risk of changes affecting unrelated application functionality.

Improved Platform Performance

The modular architecture reduced performance bottlenecks and improved system stability under increased demand. Engineering teams also gained greater flexibility to maintain and expand individual application components.
