- Optimize Search: Design and optimize search systems (e.g., Elasticsearch, vector search), balancing relevance, latency, and scalability.
- Tackle complex discovery challenges such as real-time catalog updates, search relevance optimization, and high-throughput API design at scale.
- Manage Data: Design and optimize data models across a diverse stack including PostgreSQL, DynamoDB, and caching layers like Redis (Valkey).
