Phase 22 · Build Backend Portfolio Projects
ProjectsNotification Service (Email/SMS/Push)
Part of the Backend Developer Roadmap.
Summary
A unified service for sending notifications across multiple channels — practice for third-party integrations, templating, and queue-based delivery.
How to Learn This
- 1Integrate at least two channels, e.g. email via SendGrid and SMS via Twilio.
- 2Process sends through a queue so a slow provider doesn't block your main API.
- 3Add delivery status tracking and retry logic for failed sends.
