About
I’m a senior frontend engineer who builds reliable, user-friendly interfaces and the testing infrastructure to support them. At CrowdStrike, I architected a React UI for a CLI-only provisioning workflow, replacing daily polling with status tracking and self-service error triage, and I’ve modernized internal tech tooling by migrating core React modules to TypeScript.
I also enjoy driving measurable product outcomes—whether that’s leading the Loyalty Membership Hub build at Etsy to lift cart checkouts across A/B tests, rebuilding Enphase’s lead generation funnel to increase qualified leads, or improving accessibility and usability for high-impact investigation tools at Meta. I care deeply about performance, engineering quality, and making systems easier for teams to operate under real-world pressure.
