I will design your database schema and write sql queries that work
About this Gig
A badly designed database makes every feature slow and painful later. I design clean, normalized databases that scale with your project.
I'm a database specialist (BTS in Database Computing) and web developer. I turn your business rules into a correct relational model tables, keys, relationships and write the SQL to build and query it.
Services in this gig:
Database design from scratch (ERD + relational schema)
SQL creation scripts (MySQL / PostgreSQL / SQL Server / SQLite)
Complex queries, joins, views, and reports
Fixing and normalizing an existing messy database
Converting Excel/CSV files into a structured database
You receive clean, commented files plus a diagram you can actually read and I explain the choices so your team understands the design.
Send me your project description or your current tables, and I'll tell you honestly what it needs.
