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 love bringing my ideas to life:

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.

After looking up a word, tap on any word in the definition to search for its meaning too.

Tap the star button to save the word to your flashcard collection.

Flashcards are automatically generated from your saved words for easy review.

When reviewing the flashcards, you can rate each word as 'Don't Remember,' 'Vague,' or 'Remember.' Based on your feedback, the algorithm calculates your familiarity with the word and adjusts its position in the review order, ensuring a personalized learning experience for future sessions.
