I've built and maintained Django backend architecture for an e-commerce marketplace at a global logistics technology company, developing scalable REST APIs and internal services.
I improved PostgreSQL performance by resolving N+1 query issues and reducing Django admin database load by 30%. I also implemented a CRM integration that automated real-time order-data synchronization.
I work with Celery and Redis for background tasks, integrate payment and SMS services through REST APIs and webhooks, and containerize development environments with Docker and Docker Compose. I've contributed integration and unit tests for authorization and shopping-cart modules using Pytest.
