Denis Defreyne

Hello! I’m Denis (/dəˈni/, pronouns he/him). I am a writer of fiction and non-fiction, a game developer, a software engineer, and a public speaker.

Every Sunday, I publish my week­notes, in which I reflect on the past week. Read my last entry, Wirt­schafts­iden­ti­fika­tions­num­mer, published April 27, 2025.

I created Nanoc, a mature static-site generator written in Ruby, and led the implementation of closecontact, a former COVID-19 contact-sharing solution for Berlin clubs. I’ve worked as a software engineer for SoundCloud, BCG Digital Ventures, Pitch, Shopify, and others.

Feel free to get in touch with me! If you like what I create, consider buying me a coffee.
