Hi there! 👋

Hey, I’m François Petitit - a French resident with extensive experience in software development and a wide range of passions (•‿•)

Currently, I work as a co-founder CTO of an innovative property management company : Owwner.

Before that, I spent several years as a senior Web developer at La Ruche qui dit Oui! a great ethical and fair trade e-commerce platform.

And even before that, I started my career at OCTO Technology, an extraordinary IT consultancy, as a consultant and leader of the front-end web tribe.

My main interests are web development and product design.

I hope you find something of interest by reading my articles. Don’t hesitate to leave me a message to start the conversation !

And that’s expensive. Very expensive: $99 million per year, according to the article. And generative AI, which can generate images and videos, currently generates very little revenue.
