Build reliable SQL Server databases and improve the queries that power your business software.

Since 2010, I have worked with Microsoft SQL Server and T-SQL while developing ERP systems and applications for accounting, inventory, sales, purchasing, payroll, and import management.

What I can help with: • Design tables, relationships, keys, and constraints. • Write and modify T-SQL queries, stored procedures, views, and functions. • Diagnose slow queries and improve performance through query and index changes. • Correct SQL errors, calculation issues, and data retrieval problems. • Develop database logic for business workflows and reporting. • Create scripts for agreed data imports, updates, and transfers.

How I work: I review your requirements and existing database structure, agree on the scope, and develop or improve the relevant SQL code. I test correctness using representative data and, for optimization tasks, compare performance where the environment allows.

Deliverables may include SQL scripts, updated database objects, and a brief explanation of the changes and deployment steps, depending on the agreed scope.

To get started, please share: • Your requirements or a description of the problem. • Your SQL Server version. • Relevant queries, database schema, and sanitized sample data. • Expected results and, for slow queries, available execution plans or timing information.

Please contact me before booking so I can assess the work and confirm the price and delivery timeline.
