Distributed Notification System
High-throughput backend service designed for resilient, decoupled notification delivery across multiple channels.
Technologies & Tools
C#ASP.NET CoreRabbitMQREST APIsDocker
Problem Statement
High-volume applications require reliable, asynchronous notification dispatch without blocking core transaction threads.
Role & Contributions
Backend Engineer. Designed decoupled message queues and worker pipelines for fault-tolerant notification dispatch.
System Architecture & Design
C#/.NET backend utilizing message queues and background worker services for asynchronous email and webhook delivery.
Key Engineering Decisions
- 1.Asynchronous worker pipelines to decouple API response time from notification dispatch.
- 2.Retry mechanisms with exponential backoff for external notification providers.
Challenges Overcome
- Ensuring message idempotency and preventing duplicate notification triggers under retry conditions.
Lessons Learned
- Deepened practical understanding of distributed messaging and background task orchestration.
Results & Impact
- Reliable asynchronous notification processing architecture.
