Monitor and improve data platform performance, reliability, and cost efficiency.
Collaborate with cross‑functional stakeholders to understand requirements, support analytics initiatives, and provide high‑quality data solutions.
Implement best practices for data governance, documentation, lineage, and data quality.
Stay up to date with emerging data engineering tools and technologies to continuously improve architecture and processes.
