The Business Challenge
- Managing a large product inventory
- Optimizing images for performance
- Helping users choose the right products
Technical Decisions & Trade-offs
- E-commerce Platform Selection: Selected standard catalog data structures over custom database schemas to leverage proven order and shopping cart state designs. The trade-off was managing catalog data synchronization complexities, which was preferred over building custom transaction logic.
- Database Catalog Indexing: Used relational database-level indexing for simple catalog lookups. Accepted the trade-off of higher memory usage on database nodes to avoid the operational complexity of integrating an external search engine.
Engineering Deliverables
- Lighting product catalog
- Category and style-based browsing
- Secure checkout process
- High-quality product imagery
Operational Lessons & Insights
- Deadlock Mitigation: Discovered that database queries during concurrent updates must execute in sequential order using transaction blocks to prevent locking issues.
- Schema Drift Control: Established strict migrations scripts checks to verify database schema consistency across staging and production environments.
