• Drive performance optimization across the stack: application profiling, caching, asynchronous processing, database tuning, and front-end optimization for React applications.
• Build and optimize CI/CD pipelines for automated deployment and delivery.
• Collaborate with engineering teams and stakeholders to define application architecture and technology standards.
• Troubleshoot complex application performance, scalability, and reliability issues.
• Conduct architecture and code reviews and enforce engineering best practices.
