STATUS: Seeking 2026 New Grad & Full-Time Roles

hi! i'm nathan 👋

i just graduated at uc berkeley (go bears!) studying data science & computer science. my academic interests lie in machine learning and data engineering pipelines.

currently, i'm focused on scalable cloud-native architectures, designing event-driven data systems, and actively looking for new grad and full-time opportunities. beyond writing code, i'm an avid photographer capturing urban structures and natural landscapes.

in my free time, i like to go sidequesting with my camera, hit the gym to clear my head, or travel the world.
