Database Schema Designer: From Description to Migration-Ready SQL

<!--tl&dr-->

**TL;DR:** Describe your domain in plain English — get back a normalized, index-optimized schema with migration scripts.

<!--/tl&dr-->

The 10-Second Pitch

• **What it is:** A generative agent that converts natural-language domain descriptions into production-ready database schemas.
• **Who it's for:** Backend engineers, architects, and anyone who wants to skip the whiteboard-to-DDL gap.
• **Why it matters:** Schema design is load-bearing for performance. Bad first design = expensive migrations later.
• **Stack:** Node.js agent, outputs raw SQL + migration metadata.

Database Schema Designer is a force multiplier for backend engineers. For the 80% of tables that follow predictable patterns, it's faster than writing DDL by hand.
