About this Gig

Are slow database queries, bad table relationships, or unorganized records holding your project back?

A poorly designed database causes sluggish apps, high server load, and annoying bugs. I will design a clean, normalized relational database schema or optimize your existing MySQL queries for maximum performance and speed.


What I offer:

Relational Schema Design: Normalized (3NF) structures with primary/foreign keys, constraints, and cascading rules.

Visual ER Diagrams: Clean Entity Relationship Diagrams (ERDs) generated via MySQL Workbench or dbdocs.

Query Optimization: Rewriting slow SELECT queries, fixing joins, and adding composite indexes for instant performance gains.

Custom SQL Scripts: Writing clean views, stored procedures, triggers, and complex CTE queries.

Dummy Seed Data: Providing sample INSERT scripts to test your schema right away.

NoSQL Design: Document modeling and aggregation pipelines for MongoDB or Neo4j.


Deliverables:

1. Executable, fully commented .sql scripts.

2. High-resolution ER diagram (PDF/PNG).

3. Clear instructions on running the scripts in your environment.
