About Me

I'm pursuing a Bachelor's in Computer Science at Arizona State University with a passion for building elegant, scalable software solutions. My interests span full-stack development, machine learning, and data analysis. I'm driven by the challenge of translating complex problems into clean, efficient code.

Whether architecting backend systems or exploring AI/ML applications, I'm committed to continuous learning and delivering production-ready solutions. I thrive in collaborative environments and am eager to contribute to meaningful projects that make a real impact.

Outside of software, I’m disciplined about fitness and health, lifting, running, and optimizing routines, which is the same mindset I bring to engineering: consistency, feedback loops, and measurable progress.
