Erik has been working in marketing since 2012. What started as an all-round marketer evolved through brand activations, YouTube and social media, advertising to an ever-growing fascination with how platforms work and how they keep changing.

Erik now builds complete apps and systems with AI tools like Claude Code and Cursor, without writing a single line of code.
