About Me
I am a self-taught software developer possessing over ten years of experience in software application development, management consulting, and project management in technology and chemical multinational companies working in locations across US and China. The work experiences after getting my MBA, led me down the path of learning about software in my spare time on my own initiative. I wanted to more effectively lead the digital transformation projects I was in charge of and to address my own and my colleagues' frustrations while using enterprise software. In the process, I discovered a passion for software development and also opened my eyes to its potential to streamline many inefficient processes that exist in the corporate world today. I've realized I want to be at the forefront of innovation and change rather than being a follower of it.
My Portfolio
MIRROR - Fitness Companion App

Gym goers can perform studio workouts on their MIRROR workout device using their iPhones and also work out on the go.
My Role
I developed the Find Friends feature that allows MIRROR members to find other members by searching for their user names and the several entry points that would go to that app flow. I worked together with 4 other iOS developers on the revamp of the Home Tab, taking ownership of the welcome and progress sections that are in the top of the view. Another cool project was working with the Apple Watch for the first time, by implementing dynamic loading of emojis fetched from the backend to render on the Apple Watch while a user is in a workout.
