RESUME / PORTFOLIO FRAMING
Describe what you actually did.
Implemented a queued notification service with templates, user preferences, retries and delivery observability.
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.
