- Actively participate in code reviews across frontend and backend contributions, helping establish engineering best practices in a team transitioning from a mobile-first to a full stack, web-capable organization.
- Identify and resolve performance bottlenecks, data inefficiencies, and production issues across the full stack, ensuring a smooth, reliable experience for merchant users.
- Stay up-to-date with the latest frontend technologies, trends, and best practices, applying them to enhance our merchant-facing web platform.
