In this course, you learn how to spot common performance issues and fix them early.You use clear patterns and simple steps to keep systems fast from the start of a project.
Core Ideas
You follow the Fast by Default model. It gives you a plan that builds performance into each stage of development. You avoid the old “build first, optimize later” habit.
You also learn the System Paths framework. It gives you a shared way to talk about performance across teams and tech stacks.
What You Learn
Find and Fix Slow Paths
You study common slow cases. These include slow dashboards, heavy API calls, and chains of requests that fail under load.
You learn to trace these paths and see why they break down.
Use Profiling and Dashboards
You use profiling tools to see what code uses the most time or memory. You read common dashboards so you can spot slow queries, long queues, and busy services.
Add Performance Checks to CI
You set clear performance budgets. You add tests in CI so the team sees issues before code goes live.
Review Design for Speed
You learn how to review designs with performance in mind. You check data flow, cache use, and API design. This keeps the team focused on the user experience.
Team and Culture
Build a Performance Mindset
You learn ways to talk about performance with engineers, PMs, and other partners. You build habits that help the whole team keep systems fast as they grow.
Work With Observability
You improve logs, metrics, and traces. This helps you find issues in both small services and large systems.
Handle AI Tools and Bot Traffic
You study how AI tools change load patterns. You also learn how to detect and manage non‑human traffic that can slow or break systems.
