Camera Lead Design Engineer ยท Apr 2020 to Sep 2022
Snap Inc.
Working prototypes that turned product ideas into measurable launches.
I designed and built fully functional native prototypes across Camera, Creative Tools, and Memories, then partnered with production engineering through edge cases, launch, experimentation, and measurement.

The product work
I worked where interaction design met real platform behavior. Rather than stopping at static screens, I built realistic native prototypes so teams could experience timing, state, gestures, media behavior, and failure cases before investing in production code.
The systems underneath it
The work combined Objective-C, Swift, UIKit, product analytics, anonymized logs, controlled experiments, and user research. Production engineers wrote the shipping code; I stayed closely involved through implementation, launch, and measurement.
Selected work
01Preview Filter Carousel
I designed and built the working Objective-C prototype, then partnered with production engineering through launch. Experiments increased filter impressions by 38% on iOS and 10% on Android, and increased Snaps sent with filters by 9% and 5.4%, respectively.
02Creative tools in real code
I built functional prototypes for Voice Over, Auto-Caption, Text-to-Speech, Crop, Stickers, Lens Explorer, Lens Carousel, Universal Search, and editing flows. The prototypes made behavior testable in context before the production build began.
03Research, instrumentation, and leadership
I used analytics, anonymized logs, experiments, and UX research to improve creation, engagement, and discovery flows. I also led and mentored three design engineers while partnering with product, design, research, data science, and engineering on strategy and annual roadmaps.
