About Me

I'm a Computer Science B.S graduate from UC Santa Cruz. I'm passionate about building systems that scale. My journey spans from backend architecture to full-stack development, with a focus on data engineering and cloud infrastructure.

I'm currently pursuing a Master's in Artificial Intelligence and Data Science at Leiden University (expected 2027), where I'm exploring how data driven systems and intelligent models can make technology smarter and more adaptable.
