Your product, from zero to production

A senior developer who owns your product end to end: the backend, the web interface and, when you need them, the mobile apps.

• A solid backend, built with deep Ruby on Rails expertise.
• Fast web interfaces with Hotwire (Turbo, Stimulus) and a component library.
• iOS and Android apps in Flutter when your product needs them.
• More speed from AI coding agents, kept in check by quality gates on every change.

Is your Rails application struggling to keep up with growth, or showing its age? I move it forward: holding the load, upgrading, modernizing the interface and the backend.

At Chronogolf, I designed the backend from zero to hundreds of thousands of daily users. At iDocus, I modernized the interface and the backend and started a component library.

A time-based contract, full-time or part-time.

Remote for Canada and France, with at least three hours of overlap with Paris business hours every day. Hybrid or on site in the Québec City area.

• Chronogolf, 2014 to 2018: as the first developer, I designed the backend and built the team while the company grew from 5 to more than 45 people, including 10 developers. Chronogolf was later acquired by Lightspeed.
• Homeric, since 2021: as a co-founder, I built the backend from day one, and I remain its on-demand technical advisor.
• Scribee, 2025 to 2026: I built a French e-invoicing platform from zero in Rails, and designed its iOS and Android apps in Flutter. Scribee became a state-approved e-invoicing platform in France within a week of filing.
