Overview

I've spent 8 years on iOS apps - first at Fidelity Investments, now at Greystone Software. Moved 60% of iOS traffic off a legacy monolith without a customer-facing incident. Took crash-free sessions from 96.5% to 99.6%. Before that: Expedia Group and Fidelity Investments. Most at home with XCTest and Combine. Volunteer coding coach for school students.
