• Optimize application performance, reliability, and user experience
• Work within and contribute to design systems and reusable component architectures
• Implement and manage feature rollouts using feature flagging tools
• Participate in code reviews, debugging, and troubleshooting across the application lifecycle
• Support onboarding and knowledge transfer within a large, complex application ecosystem
