About Me
Senior iOS Engineer
I'm a Senior iOS Engineer with 13 years of professional experience, the last 9 focused on iOS. I was most recently on Pinterest's Gestalt team — its iOS Design System — shipping shared components adopted by every iOS product team.
Before Pinterest, I was Tech Lead for the iOS Credit & Loans squad at C6 Bank during its 2M → 20M hypergrowth. I've worked internationally as a remote engineer since 2019, for teams in Canada and the US, and co-founded two mobile startups.
I'm most at home in shared infrastructure — design systems, modular frameworks, and the testing cultures that keep them reliable. I care about accessibility and product quality, and I bring an entrepreneurial mindset to every project.

On the Gestalt team — Pinterest's iOS Design System — I built and maintained shared UI components used by every product team, contributing to 300+ components across a library of 100+ primitives. I was the sole author of the Tag component's rewrite from Objective-C to Swift, fixed a cross-cutting bug in the video player, and drove adoption of a new snapshot-testing workflow. These components powered the experience for 500M+ monthly active users.
