About

A bit about me

I'm a software engineer who cares about doing things right whether that's migrating terabytes of enterprise data to the cloud or building a pixel-perfect React component. I thrive at the intersection of systems thinking and user-facing craft.

Currently pursuing my Master of Science in Computer Science at Stony Brook University, I bring hands-on experience in full-stack development, cloud data engineering, and building real-world products used by hundreds of people.

I hold certifications in Azure (Administrator Associate) and AWS (Cloud Practitioner), and I'm always chasing the next interesting technical challenge.
