About

Hey, I'm Louis — a full-stack developer and indie maker. I spent years as a technical lead in the AI industry before going indie. I build AI-powered tools that solve real problems for real businesses — not just demos. I care about shipping fast, keeping margins healthy, and building things people actually pay for. Currently working on new AI SaaS products in the image editing space. Always happy to connect with other indie makers and builders.

An AI car modification studio for car owners and enthusiasts.

See your dream build before you spend a cent on parts or paint.
