  • Programming skills in SQL, Python, PySpark, SparkSQL, Scala, and R for solution delivery.
  • Data wrangling expertise, including structuring, cleansing, merging, enriching, validating, and publishing data for discovery and use case development.
  • Integration knowledge, including Databricks/Azure orchestration tools and experience automating ML scripts into Data Factory and ML pipelines.
  • ML optimization skills, including optimizing ML model training scripts to reduce runtime and resource usage.
  • Automation experience, including automating predictive model validation, deployment, and implementation processes.
