Hire Ruby on Rails developers in France

I started learning Ruby on Rails because I wanted to bring my ideas to life by creating simple and effective web applications. What I love most is building projects that make sense and can truly be useful to people. I first created my personal website with Jekyll to share what I do and what inspires me. Then, I developed Quotety, a project that is close to my heart, and now I’m working on creating a game, a new challenge that pushes me to learn even more. At the same time, I’m also the founder of the podcast Art au Féminin, where I give a voice to women passionate about art. This project is important to me because it combines my interest in creativity and my desire to highlight female voices. Every day, I’m motivated by the desire to learn, grow, and contribute to projects that reflect who I am. I’m excited to join a team where I can continue to develop while making a meaningful impact.

Hey, I’m Antoine - a Fullstack Software Engineer with 5 years of experience, specializing in Ruby on Rails and React. I spent 4 years at Doctolib, France’s leading healthcare tech platform, and another year at SNCF Connect, the French national railway company (yes, more Rails ! 😄). I’m love building user-centric products. Most of my experience is with Customer Care teams, where I integrated a wide range of third-party tools: two Zendesk help centers (with SSO), Amazon Connect and Talkdesk for instant web callbacks, Intercom for live chat, Salesforce APIs for a streamlined ticketing tool, and more. I’ve also developed key features like contact funnels with smart deflection (FAQ suggestions, chatbots, streamed LLM content, etc.) and refactored some of the most legacy parts of our products. Beyond product work, I led tech debt and bug ownership initiatives, contributed to accessibility (A11Y) efforts, and led our Rails monolith modularization at team scale. I'm looking for a full remote position (FR/EU/US)
