About this Gig
Is your database running slowly, or do you need a pristine, production-ready schema built from scratch?
Poorly structured tables, missing indexes, and unoptimized queries waste computing power and stall applications. As a data professional, I build, audit, and tune SQL databases to ensure peak operational speed and flawless data integrity.
What I Deliver:
Query Optimization: Rewriting slow queries, optimizing complex JOINs, CTEs, and Window Functions.
Database Schema Design: Designing normalized structures (1NF, 2NF, 3NF) paired with clear Entity-Relationship Diagrams (ERD).
Performance Tuning: Creating efficient indexing strategies to cut execution times.
Advanced Configuration: Setting up user permissions, role-based access control, admin panel tools, and seamless data import/export (ETL) routines.
Flavors of SQL Supported:
PostgreSQL | MySQL | Microsoft SQL Server | SQLite

FAQ
What do you need from me to begin working on my database?
For query optimization, I need your slow SQL query and your table structure (DDL script or schema description). For database design, a brief overview detailing your business requirements and how your data points relate is perfect.
Will my data remain secure during an audit or migration?
Absolutely. Data security is my top priority. I highly recommend providing dummy or obfuscated data for testing purposes whenever possible, and I always strictly adhere to standard data privacy practices.
Do you provide the database structure as a visual or a script?
You get both! For schema design orders (Standard/Premium), I deliver a comprehensive, professional visual Entity-Relationship Diagram (ERD) alongside a ready-to-deploy SQL DDL script so you can build your tables instantly.
