# Thibault Fayard

Freelance full-stack developer (TypeScript, React, Next.js, PostgreSQL) for more than five years, Thibault Fayard builds inlinr alone, from Chalon-sur-Saône in France, and writes every guide on this site.

Missions for software publishers and small companies: replacing a business application more than 15 years old with a web app and moving its data to PostgreSQL, taking over and stabilising a platform before its public launch. Bachelor's degree in software engineering (CESI, 2022).

The guides on coding time and AI assistants come from what inlinr measures. The ones on invoicing in France come from billing clients by the day as a sole trader, and each one is checked against its sources.
