Experience with databases and backend data models.
Experience with automated testing across the application stack.
Familiarity with CI/CD and modern software development practices.
Experience with design systems or reusable front-end component libraries.
Familiarity with accessibility, performance optimization, and responsive web development.
Experience working in an Agile/Scrum environment.

What You'll Bring

You are a senior full-stack engineer with a strong front-end foundation and proven React expertise, combined with the ability to work effectively across the application stack.
