Picture of me
Hi! 👋

I'm Gram Liu.
Developer. Engineer. Tech Enthusiast.
About Me
Hi! I'm Gram and I build things, from web apps to full stack to IoT. I'm a senior at Carnegie Mellon University pursuing a major in Electrical and Computer Engineering. I'm a big fan of technology and how it changes the way we tackle everything from payments to health care, consistently pushing the boundaries of what we think is possible.

Outside of tech, I also really enjoy cooking! I try to do the food justice by honing the art of food photography over on Instagram.

Software Engineering Intern
May - Aug 2022
  • Built a first-of-a-kind CI testing framework for the Stripe Terminal Readers, emulating the physical readers with Android on CI for automated testing
  • Fixed flakiness on CI that two engineers tried to solve unsuccessfully over the past 12 months, improving reliability of a core test suite from 80% to 100%
  • Drove collaboration across 5 teams to scope out a key problem in the development of future emulator tests, identified potential solutions, and determined concrete steps for the fix
  • Created various developer productivity improvements such as emulator crash detection, concurrent log streaming, and faster failure detection, bringing down test time-to-failure from 1 hour to 20 minutes
