What You Bring

• From Rookie to Rocky: No previous experience? No problem. We value humility, hard work and a commitment to self-improvement over a packed résumé.

Contributions can include comments, commits, pull requests, issues, or anything else that showcases your engagement and skills. Please include your expected period of study here!
