About

I'm Louis Leschevin, a full-stack developer based in Normandy, France. I build business applications, APIs, and web and mobile interfaces with TypeScript, Nuxt, Vue, AdonisJS, Node.js and PHP. As a freelancer, I want to work with a product team over time: ship new features, integrate external services, and make existing systems more reliable. I work remotely with French and international teams. My personal projects take me deeper into data and esports. With Ward, I turn League of Legends replays into data and review tools.
