Manage ad hoc CRM data tasks including journey updates and API integrations.

Work extensively within AWS using Lambda, API Gateway, and Python to maintain and enhance integrations.

Migrate these pipelines into Airflow, dbt, and Terraform workflows.

Modernize and scale legacy infrastructure running on AWS.

Collaborate with engineering teams to ensure a smooth transition and system stability.
