ENTERPRISE SOFTWARE PROJECTS

Distributed Order Processing & Inventory Locking Microservice

95 ATS
Backend Systems Architect
Technologies: Python, Django REST Framework, PostgreSQL, Redis, Celery, Docker
  • Architected high-throughput transactional order execution engine handling 2,500+ concurrent requests/sec with zero double-allocation errors.
  • Engineered distributed concurrency lock using Redis Redlock and atomic database transactions, preventing race conditions during flash sale spikes.
  • Optimized relational database queries via Django select_related/prefetch_related and B-tree indexes, slashing p95 latency from 185ms to 24ms.
  • Configured asynchronous background queue using Celery and Redis to reliably process invoice generation, payment webhooks, and audit logs.
