Diamond Diary
Industrial diamond inventory & ledger database
An industrial inventory ledger and transaction database engineered to replace manual paper logs in diamond manufacturing. Jaimin designed a zero-drift PostgreSQL schema with Prisma, built a high-speed Hono REST API, and developed a virtualized Next.js table interface delivering sub-100ms multi-column searches to streamline daily gemstone processing operations.
// 01. The Challenge
Engineered specifically to help my Dad's daily diamond processing work by replacing manual paper logs with a zero-drift, multi-attribute transaction ledger database.
// 02. The Approach
Designed a high-precision PostgreSQL relational schema, built a fast REST API with Hono/TypeScript, and developed an interactive virtualized data table for real-time multi-column search and inventory tracking.
// 03. The Impact
Eliminated transaction calculation errors with zero decimal precision drift, reduced query latency below 100ms, and streamlined daily workflow operations for my Dad's work.
