Optimizing Frontend Performance for a Growing SaaS and Web3 Application

An application that has grown quickly often carries the cost of that growth in its bundle size and render performance; every new feature adds more code to load and more components that might re-render more often than they need to. The symptoms show up as a frontend that feels sluggish, even though nothing is technically broken.

I introduced lazy loading and code splitting so users only downloaded the code needed for the page they were actually on, rather than the entire application up front. Expensive renders were identified and optimized, often by finding components that were re-rendering in response to state changes that didn't actually affect their output. Caching strategies were refined to avoid redundant network requests, and the component architecture was reworked in places to encourage reuse instead of near-duplicate implementations that each carried their own performance cost.
