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.
