Demonstrated experience designing and building large scale production systems with solid architectural foundations.
Strong understanding of system design principles, APIs, distributed systems concepts, and cloud-native development.
Hands-on experience integrating machine learning models into production applications or services
Experience with cloud platforms, CI/CD, DevOps, or MLOps practices for deploying and monitoring applications.
Strong problem-solving ability — able to break down ambiguous problems into clear technical plans.
