Senior🎓
Top SchoolUmang Sharaf is a Lead Data Engineer with 11 years of experience building and scaling data platforms for high-throughput analytics at Chartmetric, where his teams power real-time insights across millions of artists, tracks, and playlists. He specializes in orchestrating reliable pipelines and cost-efficient infra using Airflow, ClickHouse, Snowflake, Postgres and Elasticsearch, and has driven measurable cloud cost reductions through query and infrastructure optimizations. At Chartmetric he has owned end-to-end data delivery to major label customers via AWS S3, Snowflake, Databricks and GCS while growing and managing a 10+ person Data organization. His background blends rigorous ML training from UC Berkeley (including RL work on traffic control) with hands-on engineering—from ingestion and ES indexing to production ML ranking—so he bridges research and production needs. An obsessive personal data collector and former iOS indie publisher, he brings a detail-oriented, product-minded approach to data engineering and pipeline design.
