What I'm looking for

I'm particularly interested in using AI to improve development workflows and reduce repetitive work, while keeping a strong focus on the end user.

At Instacart, I built a Kotlin Multiplatform design system from scratch for Android and iOS, with 40 reusable components. I also implemented shared device log export, helping support resolve 38% more incidents per sprint relative to baseline.

I improved product caching for discovery flows, where add-to-cart conversion grew by 24%. I also optimized complex home-screen GraphQL queries, reducing P95 loading time from 8.5 seconds to 3.9 seconds.

At Zalo, I built Android experiences for the Kiki Info AI assistant and worked on Zalo Video short-form content. I also improved chat media previews, reducing P95 load time by 30% and janky frames by 11%.

At DriveQuant, I worked on an Android white-label app and contributed to the DriveKit SDK. I integrated BLE beacon pairing and improved auto-start logic, increasing trip detection accuracy from 84% to 92%.
