Worked on Galileo, Cruise's internal simulation and testing platform used by 300+ AV and release engineers to validate autonomous vehicle software changes. Built developer tools and infrastructure to accelerate the AV development cycle.
Key projects:
• Snapshot and caching system for querying simulation output: Core infrastructure enabling migration to new internal dashboarding tool (SimRex). Achieved significant performance improvements, reducing key workflows from minutes to seconds.
• Top Movers automated scenario selection: Used heuristics to predict which test scenario results would need to be inspected, avoiding generation of large simulation output files for unchanged scenarios. Saved $2.9M/year in storage costs.
• Statistical significance testing for AV metrics: Productionized bootstrap sampling tests for determining whether metric changes were significant or required additional validation. Improved regression detection rates from 12→34% and 32→70% across test suites.
• Regression attribution system: Git-bisect-style system to identify code changes causing performance regressions post-merge, as running full simulation suites on every PR would have been time- and cost-prohibitive.
• Infrastructure optimization: Caching and deduplication improvements saving ~$2.5M annually in cloud GPU costs. Decommissioned legacy systems, removing 30,000+ lines of code
Additional contributions:
• Bar Raiser for coding interviews; conducted 200+ interviews
• Supported team through period of near-complete turnover via onboarding and documentation

Contributed to Trifacta's enterprise data transformation platform Trifacta Wrangler, the technology behind Google Cloud Dataprep. Developed and improved significant portions of the product's architecture, with a focus on REST API design, the Wrangler domain-specific language (DSL), and support for user-authored and managed data transformation scripts. Worked with Webpack, Node.js, Express, Sequelize, Postgres, Backbone, React, Hadoop, and Spark.
