- Define and apply appropriate validation metrics (e.g., accuracy, precision, recall, F1-score) to assess model performance and ensure business alignment.
- Collaborate with stakeholders to understand business needs and translate them into technical requirements, even when dealing with ambiguous or non-detailed user stories.
- Effectively communicate technical concepts and model outcomes to both technical and non-technical audiences.
- Contribute to the design and architecture of cloud-based data science applications.
- Manage code and collaborate with the team using Git, and perform tasks using Bash and the command line.
- Develop and deploy serverless components using Azure Function Apps.
