    Senior Ruby on Rails Product Engineer
    Hubflo · Freelance
    Spent more than four years helping build and evolve Hubflo, a B2B SaaS platform for client portals and shared workspaces. I took ownership of complex product work from scoping and product trade-offs to implementation, testing, and production. Selected contributions: - Built and evolved client billing features, allowing Hubflo customers to create quotes, invoices, payment requests, recurring invoices, and manage related business rules. - Led a progressive multi-currency migration, updating the application architecture to support multiple currencies across customer billing and other business entities storing monetary amounts. - Connected forms and smartdoc workflows to CRM records and custom fields. - Built notification flows across email, SMS, and push, as well as white-label mobile experiences and secure authentication flows. - Built an integrated file viewer for images, PDFs, videos and audio using Rails and Turbo, without relying on JavaScript. - Worked on asynchronous previews, secure ZIP imports, APIs, integrations, performance, and security hardening. Owned complex product areas end to end, from initial requirements to production delivery.

    ParseMyMail · Self-employed
    I designed, built, and launched ParseMyMail, a Ruby on Rails SaaS for automation professionals that turned incoming emails into structured JSON data for use in their workflows. I owned the product end to end: initial positioning, UX, architecture, Rails development, landing page, deployment, and early user testing. The product didn't reach the adoption and retention needed to justify continuing it, so I eventually shut it down and archived the code publicly. More importantly, the experience changed how I approach new products. I now put much more emphasis on validating the problem and getting real commitment before investing heavily in development.

    FRN Ingénierie · Freelance
    I returned to Astrabaz for a follow-up engagement focused on evolving its interactive map module. I expanded geographic exploration to a global scale, updated the Mapbox integration, added a globe view, enriched international categories and datasets, and improved existing user flows and performance.

    I returned to Codeur for a freelance engagement, contributing to several existing Ruby on Rails applications across the group. I quickly got back up to speed on established codebases, then delivered new features and maintenance work with a high level of autonomy. The engagement also included work on existing Vue.js components.

    Ruby on Rails & Vue.js Product Engineer
    FRN Ingénierie · Freelance
    In a three-person team made up of a non-technical founder, another engineer, and myself, I designed the software architecture for Astrabaz's main interactive map module and implemented it for a financial-market monitoring platform. I owned the feature end to end: domain modelling and Rails APIs, the Vue.js and Mapbox interface, geographic views, filters and search, aggregated trends, charts, asynchronous loading, responsive behaviour, and keyboard navigation. The work required understanding a complex financial domain, turning it into a usable product experience, and moving forward with a high level of autonomy.

    Ruby on Rails & Vue.js Developer
    Codeur · Permanent
    I joined Codeur for my first Ruby on Rails developer role, working across several products including Codeur.com, Graphiste.com, Redacteur.com, and Facture.net. I contributed to new features, maintenance, and the evolution of existing Rails applications. I also designed and built the first version of Traduc.com, taking responsibility for a complete product early in my career. That experience taught me how to move between multiple products, understand different business needs, and take ownership beyond individual tickets.

Kind words

    Co-founder & CTO @ Hubflo
    Robin is the kind of developer you can rely on with complete confidence. Over our 4 years working together, I’ve especially appreciated his autonomy and his ability to scope and deliver complex projects. Highly skilled in the Ruby on Rails and full-stack ecosystem, his input is always spot-on, whether on code or product strategy. Always positive, approachable, and smiling, he’s a true driving force for any tech team. Thanks for these 4 years, Robin!

    Elorri Margeon
    Customer Care & Product Manager @ Hubflo
    I worked with Robin for 4 years, and as the Product Manager on the team, what I valued most wasn't just his code — it was how he thought about the product! He never took a ticket at face value. He'd ask why we were building something, push back when it didn't make sense, and often came up with a better angle than the one we started with. And beyond the work, he's simply someone you love having on the team: a clear, thoughtful communicator, genuinely easy to collaborate with, and the kind of calm, positive presence that lifts everyone around him. That mix of strong engineering and genuine product thinking made him a true partner, not just an executor. If you want a developer who actually thinks about product, not just tickets, Robin's your guy! 💎
