History

Where the work happened

2023 — nowNew York, NY

Intuit Mailchimp

Software Engineer II

Forms and SMS platform. Features here ship across a React microfrontend, a legacy Dojo app, and the PHP monolith — often all three at once, often under legal review.

2022 — 2023New York, NY

PayPal

Full-Stack Software Engineer

Merchant onboarding. Built the Google One-Tap sign-up integration alongside Google's engineers, then found the mobile bug that was quietly blocking its launch.

2021 — 2022Buffalo, NY

Avarint

Software Engineer

Aerospace defense modeling. Rebuilt DIADS — a ten-year-old simulator for sensors tracking incoming aircraft — with a seven-person team, so it finally ran in a browser.
