About

Making tech feel
approachable.

I quickly build websites and webapps for individuals and small businesses, focusing on clean design and real-world usability. Alongside development, I tutor students in coding, breaking down complex concepts into something actually understandable.

My goal is to make tech feel approachable — whether you're using it or learning it.
