FAQ
Can you fix existing PostgreSQL queries?
Yes. I can investigate SQL syntax errors, query logic problems, joins, filters, and other agreed issues.
Can you design a PostgreSQL database schema?
Yes. I can design tables, relationships, constraints, and indexes for a small, clearly scoped application.
Do you support Neon and Supabase?
Yes. I can help with PostgreSQL database setup and SQL-related integration requirements on these platforms.
Can you work with Go or Node.js applications?
Yes. I can help integrate PostgreSQL queries with existing Go or Node.js backends, subject to project scope.
Do you need access to my database?
Not always. Schema definitions, sanitized sample data, SQL queries, and error messages may be sufficient. Never share passwords or production secrets.
Can you optimize slow SQL queries?
I can investigate query structure and indexes. Performance improvements depend on the schema, data, execution plan, and testing environment.
Will you modify my production database?
Production changes require separate planning, backups, authorization, and a safe rollback approach. They are not included by default.
