## Work Experience
### Software Engineer @ Airtable
Jan 2024 – Present
Shipping AI features at Airtable.

### Software Engineer @ Dopt
Jan 2024 – Jan 2024
Built product infrastructure for a drop-in context-aware AI assistant, helping B2C SaaS companies enhance their end-user experiences through intelligent tutorials, feature announcements, and upsells.

### Senior Software Engineer @ Cruise
Jan 2019 – Jan 2023 | San Francisco Bay Area
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
