React Performance Sprint

Despite what many companies think, poor frontend performance isn't 'just' a technical concern. It's mainly a business issue – and a very serious one. An unresponsive product can impact revenue, operational costs, and customer satisfaction.

During a 2-week sprint, our team will review 48 performance issue types in React, spot bottlenecks, and come up with a detailed improvement plan.
