System Architecture

A showcase of distributed systems design, asynchronous processing pipelines, and scalable cloud infrastructure.

Asynchronous Export Pipeline

To handle long-running operations like bulk data exports and financial reconciliations, I decouple heavy computations from the synchronous request-response cycle using Celery and Redis. This ensures API latency remains sub-100ms regardless of background workloads.

Engineering Impact

Before implementing this architecture, complex administrative exports caused synchronous timeouts, degrading the platform for active users. By decoupling the export process, API timeouts were completely eliminated, and users gained real-time progress tracking via Redis polling.

Standard AWS Production Architecture

A standard scalable and fault-tolerant infrastructure design for enterprise web applications. Designed for high availability, utilizing managed services to minimize ops overhead while maximizing reliability.

Key Components

  • Load Balancing: ALB distributes incoming traffic across multiple EC2 instances across different availability zones.
  • Data Persistence: Amazon RDS (PostgreSQL) deployed in Multi-AZ for automatic failover and automated backups.
  • Caching & Task Broker: ElastiCache (Redis) handles session caching and acts as the Celery message broker.
  • Storage & Comms: S3 for secure static/media asset delivery, and SES for transactional email dispatching.
