CommerceX
The Bottleneck
"Traditional monolithic commerce platforms suffer from tight coupling, making them difficult to scale and prone to single-point failures."
Key Features
Event-Driven Communication via Apache Kafka
Database-Per-Service Pattern (MongoDB, PostgreSQL)
Centralized API Gateway with Rate Limiting
Distributed Tracing & Monitoring Integration
Redis-based High-Performance Caching Layer
The Architecture
Architected a decentralized system using Node.js and Kafka, implementing a database-per-service pattern and asynchronous event streaming.
Overcoming Challenges
Managing eventual consistency across multiple distributed databases.
Handling partial system failures without impacting customer experience.
Implementing complex saga patterns for multi-service transactions.
Protocol & Process
Defining service boundaries using Domain-Driven Design (DDD).
Designing schemas for Order, Product, and Payment services.
Implementing Kafka producers/consumers for asynchronous workflows.
Deploying on Kubernetes with auto-scaling configurations.
Engineered Impact
Achieved 99.9% fault isolation and significantly reduced system latency through Redis read-aside caching.
