Experience with PostgreSQL and TypeORM, including queries, relationships, and migrations.
Experience troubleshooting, maintaining, and enhancing established production applications.
Understanding of JWT authentication, secure cookies, and common web-application security risks.
Experience writing automated tests and preventing regressions.
Ability to work independently, communicate clearly, and take ownership of work through production release and support.

Preferred Qualifications

Experience with Strapi or another headless CMS.
Experience with Redis, BullMQ, or background job processing.
Familiarity with AWS-hosted applications.
Experience with customer portals or multi-customer applications.
Experience with application monitoring and production logging.
