Backend
Documented REST endpoints with request validation.
/01 THE PROBLEM
Problem & Friction
Legacy warehouse queries crawled across tens of thousands of rows, so a simple stock lookup could stall the operations team.

RedisCaching in front of repeated lookups
/02 SYSTEM DESIGN & ARCHITECTURE
Architectural Breakdown
- NestJS modules with DTO-validated endpoints
- PostgreSQL as the relational store
- Prisma ORM for typed queries and migrations
- Redis caching in front of repeated lookups
/03 IMPLEMENTED SOLUTIONS
Resilience & Outcomes
- Indexes were aligned to the query shapes that actually ran on the hot paths.
- Prisma queries were rewritten to stop over-fetching rows the caller never read.
- Critical stock levels emit notifications instead of waiting to be noticed.
