Company: Instacart
Ankit is a Software Engineer at Instacart, currently focused on building product experiences that make it easier for customers to shop healthy groceries aligned with their wellness goals.
Previously, he helped scale Instacart’s search infrastructure on a sharded PostgreSQL cluster, designing a hybrid retrieval system that combined full-text search and pgvector-based semantic search. What makes this system unique is its consolidation of semantic and lexical retrieval into a single Postgres-based stack. Eliminating the need for specialized datastores, simplifying operations, and improving relevance.
