## Work Experience
### Senior Software Engineer @ Snowflake
Jan 2024 – Present

### Software Engineer @ Snowflake
Jan 2020 – Jan 2024 | San Mateo, California, United States
I spent 5 years working on the Snowflake web interface. Some of my accomplishments included:

• Worked with two other engineers as the frontend tech lead for the private preview of private listings, the Snowflake feature to securely share data and applications with selected consumers.
• Implemented code splitting, improving p75 LCP by half a second and preventing performance from degrading as we horizontally scaled the UI.
• Led a multiquarter cross-organizational initiative to improve developer experience in our frontend repository, taking p95 PR build time from an hour to 12 minutes and improving developer satisfaction ratings by 25%.

I transferred in July 2025 to our engineering systems organization to focus on developer experience full-time.

### Software Engineer @ Zeus
Jan 2019 – Jan 2020 | San Francisco Bay Area
I worked at Zeus Living for just over a year before being laid off due to the coronavirus pandemic. Zeus Living was a Y Combinator-backed startup that provided fully-furnished housing to business travelers. At Zeus, I implemented promo codes on leases in partnership with the marketing team, bringing in $1.3M in additional lease revenue. I also designed and built the frontend and backend for a seasonality curve management system, allowing the pricing team to maximize occupancy and profitability on listings.
