About Me

Full stack software developer with experience building web, mobile, and backend solutions for a variety of industries. Comfortable working independently or with a team, quick to learn new tools, and focused on creating solutions that work well and are easy for people to use.

When I'm not working, I enjoy being outdoors, playing sports, and listening to music. I like trying new experiences and keeping life balanced between work, health, and personal growth.
