· Proficient in view layout and rendering technologies (e.g., responsiveness, progressive enhancement, browser/device support). Knows when it is appropriate to make graceful fallbacks.

· Understands how to optimize the delivery of code and assets (e.g., images, fonts) to a browser or device (e.g., lazy loading assets, using CDNs, caching, compression, etc.).

· Understands how to be efficient with resource usage (e.g., application impact on memory and CPU, caches appropriately, respectful of customer's devices, etc.).

· Knows how to instrument software with real user metrics to reflect the customer experience.
