AI & Search EngineeringProduction Case Study

Natural Language Search for Market Intelligence

A production-grade semantic search system that enables non-technical stakeholders to query complex financial data using natural language queries instead of rigid database filters. Built with OpenAI embeddings, vector similarity, and hybrid search algorithms.

The Problem

Unlocking Complex Databases for Business Users

Finding investors in "agritech sector with investments in the last 5 years" previously required navigating multiple dropdown menus, selecting date ranges, and manually applying industry filters.

The core challenge was communication: while the underlying database required rigid SQL queries, business users naturally think in conversational plain English.

The Solution Strategy

Semantic Vector Matching & Hybrid Search Architecture

I engineered a semantic search layer directly integrated with PostgreSQL using OpenAI vector embeddings. Every entity in the database is converted into a 1,536-dimensional vector representing its semantic meaning.
