Code Health & Monitoring: - Actively monitor deployed code using tools like Sentry or Rollbar, and manage backend maintenance to ensure code health and stability. Maintenance: - Handle complex system maintenance, including debugging, carefully updating WordPress and plugins, and testing all changes locally to avoid critical client feature breaks. Integrations: - Manage and maintain complex integrations, including APIs and webhooks. - A significant part of this role involves real-world integration debugging - troubleshooting webhook failures, API errors, data transformation issues, and authentication edge cases in live production environments, not just building integration.

Problem Solving: Strong problem-solving skills with a proven ability to navigate complex, legacy systems and drive issues to resolution without requiring a full rewrite. - Mindset: Detail-oriented and operationally minded — willing to dive into inherited codebases, take full responsibility for end-to-end impact, and monitor deployments carefully with a production-first attitude. - Soft Skills: Ability to balance technical depth with clear client communication and expectation management.
