About this Gig

do you need a solid SQL Server database that integrates perfectly with your backend? Lets build it right.

What I can help you with:

  • Database Design from Scratch: Clean, normalized relational schemas (1NF to 3NF) built to handle complex business logic without redundancy.
  • Stored Procedures & Programmability: Writing secure, optimized SPs and functions ready to be hooked into your API layer (ASP.NET Core, Spring Boot, Node.js, etc.).
  • Schema Refactoring & Modifications: Updating existing databases, adding new features, or fixing broken schemas without breaking production.
  • Complex Queries: Writing efficient JOINs, subqueries, and aggregations for reporting or data retrieval.
  • Performance & Integrity: Implementing SQL transactions to ensure data safety, plus proper indexing and constraints.

Why work with me?

  • I understand how databases connect with the backend (services, repositories, and APIs), not just isolated tables.
  • Clean, readable, and commented SQL scripts.
  • Crucial: Every project is different. Please message me before placing an order with your requirements or current schema so I can give you an accurate quote and timeline.
