Cost optimization for Snowflake and Databricks. Early-stage startup, Silicon Valley.

• Built the end-to-end Databricks ingestion pipeline — jobs, clusters, SQL warehouses and queries — landing in Iceberg, modeled with dbt/Trino, served from ClickHouse.
• Shipped Auto-Tune: automatic right-sizing of Databricks clusters and SQL warehouses, with a crash-safe apply/rollback state machine and audit trail, validated against live workspaces.
• Migrated 100+ hand-written metrics to a dbt MetricFlow semantic layer; A/B-validated 100% data parity before cutover.
• Built multi-cloud billing ingestion for AWS, Azure and GCP (FOCUS spec) and Spark event-log analysis down to individual query plans.

Fitness app for athletes, shipped on the iOS App Store.

• Built the app with React Native, Expo and Django; 1,000+ beta signups, 6 elite trainers onboarded.
• Live GPS route tracking, Apple Watch sync via HealthKit, forum and real-time chat.
