Software engineer in Phoenix, Arizona. I build backend services at American Express by day and study AI/ML at UT Austin by night.

Say hi!

/ about me

Currently, I'm a Software Engineer at American Express, where I build backend services and APIs that power Amex Offers, helping move offers from creation to card member experiences. Previously, I worked at Microsoft and Target.

Here are some technologies I have been working with:

  • Java
  • Python
  • React
  • TypeScript
  • Docker
  • PostgreSQL

In my free time, I enjoy playing soccer, running, and exploring fashion.
