--- title: "Work: client stories and recommendations | Olivier Buffon" description: Client stories told by outcome, from Chronogolf to Scribee, a State-approved French e-invoicing platform, with recommendations from the people I worked with. url: https://olivierbuffon.com/en/work/ lang: en --- [Olivier Buffon](https://olivierbuffon.com/en/) # Work Client stories told by outcome, each followed by recommendations from the people I worked with. iDocus and Scribee ## An e-invoicing platform approved by the French State within one week of filing ### iDocus, 2024 to 2025 iDocus is a pre-accounting solution for accounting firms and businesses: it processes their invoices and bank statements so they no longer key in accounting entries. Years after Neatops, Thomas Andrieu, CTPO of iDocus and Scribee, wanted to work with me again, offering me new contracts. Working full-time from October 2024 to November 2025, I modernized the iDocus UI and backend, and started its component library. ### Scribee, 2025 to 2026 [scribee.tech](https://scribee.tech/) Under the French e-invoicing reform, every French company must be able to receive e-invoices through an approved platform from September 1, 2026. As a full-time senior full stack developer, I built Scribee's platform from zero with Ruby on Rails, MySQL, ERB views, a custom ViewComponent component library and Hotwire (Turbo, Stimulus). I also built its iOS and Android apps in Flutter, which I designed too; they are not in the stores yet. For OCR and the processing of uploaded documents, I integrated Mistral AI, because the platform needed a European provider. I designed the team's agentic workflow: skills, agents, orchestration and quality gates on every change, so a small team shipped features and fixes with confidence. Scribee was approved as a "Plateforme Agréée par l'État" (a State-approved platform) within one week of filing. > Très bon développeur Ruby on Rails, Olivier a participé à des projets d'envergures, dans le domaine de la GED, des réseaux sociaux et Big Data. Très bonne capacité d'initiative et bonne autonomie. Olivier est rigoureux et fournit un travail de qualité ! Translated from French A very good Ruby on Rails developer, Olivier took part in large-scale projects in document management, social networks and Big Data. Strong initiative and good autonomy. Olivier is rigorous and delivers quality work! Thomas Andrieu Founder & CEO at Neatops Chronogolf, 2014 to 2018 ## From zero to hundreds of thousands of daily users In 2014, Chronogolf was a startup of 5 people building software for the golf industry. As the company's first developer, I designed its backend in Ruby on Rails, with PostgreSQL, Elasticsearch, Redis and Sidekiq, and scaled it with the product. I also built the development team as the company grew. The backend went from zero to hundreds of thousands of daily users, and the company from 5 to 45+ people, including 10 developers. Chronogolf was later acquired by Lightspeed. > Olivier joined Chronogolf on a full-time basis in 2014 when we were a small startup of 5 employees and played a crucial role in allowing us to scale to a team of 45+ individuals including 10 software engineers. Over a tenure of 4+ years with Chronogolf, Olivier demonstrated an incredible capacity to adapt with the growth of the company. Olivier is a natural leader and creative thinker who has the best interest of the business in mind when leading any project or mandate he is taking on. Beyond his strong technical capabilities as a backend engineer, he is also an altruistic colleague who leads by example. It was a privilege to work with him over the years. Jean-David Saint-Martin President at Lightspeed HQ > It was a great pleasure working with Olivier during our time together at Chronogolf. His out-of-the-box thinking and openness to involve everyone in his decision process was a testament to his character. He will truly be missed. David Hope General Manager, Golf at Lightspeed HQ Homeric, since 2021 ## A backend built from day one, and a technical advisor who stayed Homeric helps organizations run large-scale transformations: interactive playbooks rolled out across teams, automated follow-ups and real-time tracking of how practices are adopted. As a co-founder, I built its backend from day one, in Ruby on Rails with PostgreSQL and GraphQL. I am still its on-demand technical advisor. ## Other engagements ### Mirego: Canadiens de Montréal, vHub and La Presse Mirego is a multidisciplinary development, strategy and design team, based in Quebec City and Montreal, that builds digital products, web and mobile apps among them, for its partners. As a Mirego employee, I worked in Elixir and Phoenix on the backend of the Canadiens de Montréal mobile app: news, scores, exclusive content and ticketing. I also worked on vHub, a trailer-sharing platform for the transportation industry, in Elixir, Phoenix and React. For La Presse, which had become a non-profit, I worked on its new way of funding itself through donations, which lets anyone support the news outlet with a one-time or recurring donation. ### Petal: a care platform ready for thousands of users Petal gives healthcare organizations a secure platform to orchestrate patient care workflows in real time. As a backend developer in Ruby on Rails, I helped the team build a scalable, reliable platform that can handle thousands of users. > Olivier a été un atout majeur dans notre équipe. Il a été d'une rapidité et d'une efficacité hors-pair en plus d'avoir saisi l'ampleur notre écosystème dans un délai très court. De plus, il a démontré une très bonne capacité d'analyse tout au long de son mandat. Je le recommande vivement! Translated from French Olivier was a major asset to our team. He was remarkably fast and efficient, and he grasped the scope of our ecosystem in a very short time. He also showed very strong analytical skills throughout his engagement. I highly recommend him! Eric Proulx Technical Architect at Petal > What a power house. On the dev team, Olivier not only takes on the hardest tasks on the list, but also takes on initiatives that need to be done that others are not seeing. He truly leaves things much better than he found them, taking the time to do it right. Also, he's been a mentor for me. Taking the time to answer questions, teach me things, and understand that this time is an investment for the team. It's truly a pleasure working with Olivier, and a highlight of working on this team. This is the standard all devs should aspire to become. By his consistency and the way he applies himself, he is the definition of a senior developer that I aspire to emulate, and provides me with the insight of what characteristics to look for when I hire senior/lead devs in the future. Denis Daigle Fractional CTO ### Avo: a long-requested feature, in open source Avo is an open-source framework for building admin panels in Ruby on Rails. I helped the core team ship a long-requested feature: the TipTap rich text editor. ## More recommendations > J’ai eu l’occasion de constater le travail d’Olivier.
