Experience & Projects

These are various work experiences and projects that I've worked on. I am always looking for new opportunities so feel free to reach out to me!

Walmart Labs


For Walmart Labs, I built a feature application that allows over 35 million customers a year to track the status of their car order. I'm really proud of this project because I worked from end to end and created both the frontend and backend. I was guided by Full-time engineers but was allowed to take full ownership of the project. After completion, I demoed the app in front of over 500 employees in two different Senior VP conferences. I enjoyed juggling the different teams I had to work with and learning new technologies throughout the project. I worked with UI/UX, app integration teams, IOS, Android, backend security, store directors, and marketing For more technical details checkout my resume description!
