Hello 👋🏻 My name is Dan Vega, Java Champion, Spring Developer Advocate, Husband and #GirlDad based outside of Cleveland OH. I created this website as a place to document my journey as I learn new things and share them with you. I have a real passion for teaching and I hope that one of blog posts, videos or courses helps you solve a problem or learn something new.
