FAQ
Can you work on an existing Java/Spring Boot project?
Yes. Please share the repository or source code, setup instructions, database schema, logs, screenshots, and a clear description of the expected behavior.
Can you design the database for a new feature?
Yes. I can design MySQL tables, indexes, SQL queries, and backend data models based on your business requirements.
Can you deploy changes to production?
I can provide deployment guidance. Direct production deployment is possible only if we agree on scope, access, backup, and rollback plan first.
