RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Implemented a production-style checkout flow with validated forms, resilient states and accessible interactions.
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.
Payment sandbox
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Localization
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
Analytics events
Add only if it strengthens the engineering story instead of delaying a finished, deployable core.
