Wealthfront Android App

https://play.google.com/store/apps/details?id=com.wealthfront
This is an Android client for all of Wealthfront's offerings, including investment management, cash account, and financial planning. I collaborated with a team of five to fifteen people over the four years I was there and worked on most parts of the app, from writing new features to updating and refactoring aging infrastructure. I recently kick-started the design system team to standardize our UX and UI across our growing app on all platforms (Android, iOS, and web).

Stickers Habit Tracking App

A cross-platform mobile app to help people form and maintain new habits. The app focuses on gentle positive reinforcement of a new habit rather than adding stress to an already stressful goal. It is my first foray into multi-platform development and a continuation of my experience designing for Android and iOS. It's a hobby project but will be published in the App Store and the Google Play Store soon.

Wearable Stress Tracker

For my capstone project in college, we were tasked with creating a wearable stress tracker, both the hardware and software. Our prototype relied on three biosignals that we decided to use based on the available research:

• Heart rate variability: the difference in heart rate between breathing in and breathing out
• Galvanic skin response: also known as skin conductivity, or how much sweat is present
• Electromyography: how tense particular muscles are

The prototype was a functional Arduino board with all the necessary sensors and analyzed the data through a connected laptop. I also learned a lot as the team's elected leader.
