I will test databases with sql and deliver a data integrity QA report

Need confidence that your data is accurate, consistent, and ready for release? I test databases with SQL and deliver clear, actionable QA findings.

I am Tahmid, a Principal Software QA Engineer with nearly five years of experience across fintech, CRM, advertising, and government software. I validate backend data against requirements and investigate defects with reproducible evidence.

Coverage:

- CRUD operations and business rules

- SQL queries, joins, aggregates, and filters

- Data integrity, nulls, duplicates, and constraints

- Referential integrity and relationship checks

- Migration, import/export, and reconciliation checks

- Boundary, negative, and regression scenarios

Deliverables include SQL test queries, validation results, prioritized defects with reproduction steps, expected versus actual results, evidence, and a concise QA report.

Please share the schema or data model, test environment, read-only credentials, sample data, and priority tables or workflows.

Functional database testing and reporting only; no destructive production changes.
