Improve slow queries and unreliable data workflows in your SQL Server or PostgreSQL application. I bring professional .NET/database experience with relational schemas, bulk ingestion and migration, Entity Framework and production troubleshooting.

Scope • SQL query and execution-plan review • Indexing and relational schema improvements • Entity Framework / EF Core query behavior and migrations • Validation and consistency in ingestion or migration workflows • Database integration with existing C#/.NET APIs

Deliverables • A prioritized assessment of the agreed bottleneck • Reviewed SQL, index or application-query changes • Before/after timings or execution-plan comparisons on representative data where access permits • Verification steps and migration/rollback notes for any proposed schema changes • A concise handover explaining the changes and tradeoffs

Process and pricing Send your database engine/version, affected workflow and sanitized query or error details. We agree on a focused milestone, representative test data, estimated hours and delivery dates before implementation. $25/hour. Improvements depend on the workload and environment; no fixed speedup is promised. Production changes require your normal review and deployment approval.

Relevant work PostgreSQL schemas, SQL performance and ingestion/migration contributions on ABIS, plus PostgreSQL/EF Core migrations and indexing in my independently launched SachAI platform. Employer code and private records remain confidential.
