I was the sole iOS engineer who built the Category Label feature on the IG iOS App. You can see this feature on most influencer and business profiles. It allows users to explore more accounts within the similar categories as the current profile. During the first two weeks of testing, the feature achieved an 8% click-through rate among over 40 million users and demonstrated a statistically significant improvement in engagement with professional profiles, particularly in the number of new follows.
I was the UX engineer that worked on the entertainment-related search result on Bing. During the COVID-19 lockdown, I improved the Bing UX by warning users about theater closures and theater-related search results.
I was an software engineer at Amazon Go, the world's most advanced automated convenience store.
I built features such as Notifications, Special Offers, and the Menu/Discover tab on the Amazon Go app.
Below are commemorative posters signed by the engineers on the projects to celebrate these successful launches.
I redesigned the Health page of the app to address the issue of low user traffic and increase user engagement.
I designed the new marketplace page, addressing the client's need for a more business-focused shopping experience.
I designed a new feature for managing disability certificates, making the process easier and more accessible for all users.
I revamped the bank's mobile homepage for better user accessibility and experience for users with limited tech proficiency.
Over the past decade, I've developed numerous web and iOS apps as side projects. Among these, the Flashcard Dictionary app stands out as my proudest achievement. This app helps users expand their English vocabulary by testing their familiarity with words through dynamically generated flashcards and my custom memorization algorithm. I created it to address my own need for a more effective vocabulary tool, and it has since resonated with a global audience, amassing over 50,000 downloads—primarily in China and the United States.
