Hi,
About Me
Product-minded full‑stack engineer shipping end‑to‑end: APIs, auth, UI, analytics, and SEO. I build with Ruby on Rails, React/Next.js, and Flutter, focusing on performance, DX, and measurable impact.
I launched Captain Ruby, a Rails content platform reaching ~1.1k monthly visitors, and I’m preparing the private beta of FitSpotter (Flutter + Rails API) with secure auth, real‑time features, and a clear monetization plan. I’m active in the Toulouse.rb community and enjoy speaking about building reliable products.
Comfortable across the stack: Rails 7/8, PostgreSQL, RSpec, JWT/DeviseTokenAuth, Sidekiq/Redis, Tailwind CSS, GA4/SEO/RSS, Firebase, and basic Stripe/AdMob. Based in Toulouse, open to impactful collaborations.

A clone of the popular vacation rental website Airbnb. Users can create and manage listings, book and manage reservations, and leave reviews. The app uses the Mapbox API to display listings on a map and Strip for the secure payments. This Airbnb clone is a very complete MVP which was created following the tutorial by American YouTuber Chris Jeon (TypeFast).
