Description

Ruby on Rails developer for over 25 years, I design professional websites and custom applications.

I have been a Ruby on Rails developer for over 25 years. I developed and maintained paris.fr — the official website of the City of Paris — for 6 years, and built the entire back-office for slate.fr.

What I do:

Professional websites for VSEs, health practitioners, artisans, and SMEs — with online appointment booking, Stripe payment, impeccable responsiveness.

Custom web applications in Rails 8 — dashboards, back-offices, business tools, REST APIs. For startups, media, and local authorities.

Taking over and modernizing existing Rails projects — version upgrades, refactoring, optimization, hosting migration.

My stack: Rails 8, Ruby 3.3, Hotwire (Turbo + Stimulus), Tailwind CSS, PostgreSQL, Redis, Sidekiq, Devise, Stripe, Render, RSpec.

Why me:

Verifiable references: paris.fr, slate.fr — sites in production with millions of visitors.

I deliver quickly thanks to a proven technical foundation and a standardized stack.

I stay after delivery: hosting, maintenance, updates, support.

Based in Nantes, I work remotely with clients throughout France. Have a project? Contact me, I'll respond within 24 hours.
