  • Rationalize SAS and Alteryx coexistence by removing outdated SAS components and migrating useful transformations into consistent, maintainable Alteryx logic. Help eliminate duplication and reduce cross-platform complexity.
  • Support and improve the deployment and release process by increasing automation coverage and quality checks, making deployments safer, faster, and more predictable.
  • Apply and reinforce documentation standards for datasets and workflows, ensuring consistent naming and clear descriptions for a shared understanding, easy discovery, and effective usage by every squad member.
  • Establish and maintain robust monitoring systems to track data quality and performance, enabling timely identification and resolution of issues.
  • Oversee the management of daily batches to ensure consistency, synchronization, and efficient resource utilization across different environments.
