Meet Your Instructor

Johan Svartdal

I'm a software developer with over 10 years of experience, currently working at a major bank in Norway where I build enterprise-grade applications daily.

Every year, I've been dreaming of creating an advent calendar for developers — something that would make learning fun, engaging, and achievable for busy professionals like us. After years of planning and preparation, Codemas was born.

I believe that consistent, bite-sized learning is the key to mastering any technology. That's why each Codemas challenge is designed to take just 20-30 minutes, so you can fit it into your busy schedule while still making real progress.
