• GCP Ecosystem Expertise: Deep experience with the Google Cloud analytics suite-specifically BigQuery, Cloud Storage (GCS), Cloud Composer, Pub/Sub, and Cloud Functions/Run.
• BigQuery Optimization: Advanced understanding of BigQuery architecture, DDL/DML, partitioning, clustering, slot allocation, and query cost-control strategies.
• DevOps & Version Control: Proficient with Git, CI/CD pipelines, and modern software development workflows.

Preferred Qualifications:

• GCP Certification: Google Cloud Certified Professional Data Engineer (highly preferred).
