Killian Paulic
I build apps and AI tools. I work with founders launching their product, and with companies on their AI projects.

I’ve been a developer for 5 years and freelance since 2024. I’m based in Rennes and work remotely most of the time, in French or English.
Propell is the name of my business. I build your projects myself and I work with AI every day. You call me directly when you have a question.
