RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Improved frontend loading and interaction performance using profiling, code splitting and measurable performance budgets.
Use this as a starting structure, then replace it with your real implementation details, metrics and constraints. Do not claim outcomes you did not measure.
STRETCH GOALS
Go deeper if the core is already solid.
RUM telemetry
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Edge caching
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Bundle CI gate
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
