I’m a 32-year-old Computer Engineer living just outside of Boston, MA. D&D 5e is my favorite TTRPG system, therefore, most of the articles written by me will involve that in some way. That being said, I do dabble in a few other systems, so posts discussing those systems and their mechanics may pop up every so often. Some of these systems include the Star Wars RPG and Apocalypse World.

I do also design and host online D&D 5e games that thousands of people across the world attend each year.

D&D has been my passion for over 18 years now and I have been interviewed by many of the worlds experts.
