Hi, I'm Louis. I'm an AI engineer and I build my own products.
About me
I'm an engineer from EFREI Paris, specialized in Big Data & AI. These days I'm building HireLayer and TranslateMyImage, two AI products I started myself. What I enjoy most is owning things end to end: the code, but also the product, the pricing and the talks with customers. I also take on a few freelance projects.
