A performance engineer helps make apps run faster and use less memory. When a website or program feels slow, this skill finds what is causing the delay. It then applies fixes like caching, indexing, and code splitting to improve speed.
Anyone who builds or maintains software can benefit. Whether you are a developer, a tester, or a project lead, you can use this skill to spot bottlenecks in databases, APIs, or frontend code. The goal is a smoother experience for users.
The process starts by measuring current performance. Then it identifies the biggest slowdowns. After applying optimizations, it verifies the improvements. This way you know the app is truly faster and more efficient.
