About

Who I am

Test Engineer

Quanta

Born in Minnesota, raised in San Jose. I graduated from UC Merced with a B.S. in Computer Science & Engineering, driven by a lifelong passion for building things with code. I'm passionate about software development and always seeking opportunities to grow as a programmer, whether through fun side projects or building polished software. Ultimately, I aim to create work that bridges the gap between humans and technology.

Outside of engineering, I spend time ice skating, watching hockey, going hiking, swimming or playing video games. I make sure to keep myself active and healthy while away from the computer.
