About
I’m Louis Cathala, a full-stack engineer with over 11 years of experience, focused on web development since 2014. I specialize in JavaScript, Node.js and React (Next.js/Remix.js), and enjoy building efficient, scalable applications. I also have experience with Tailwind CSS, Sanity, and CI/CD tools like GitHub Actions and GitLab CI. I’ve delivered Shopify solutions ranging from simple theme updates to custom apps and extensions. I value stable, well-tested solutions and love exploring new frameworks while prioritizing performance.
I thrive in collaborative environments and continuously seek opportunities to learn and grow as a developer, keeping a strong focus on maintainability, scalability, and delivering value for clients.
