• Solid understanding of relational databases (e.g., MySQL, MariaDB, PostgreSQL, or SQL Server), including database design, SQL querying, and REST API development (GraphQL is a plus).
• A strong sense of code quality with mandatory hands-on experience in testing, including frameworks such as Jest, Vitest, or Node’s built-in testing framework.
