Behind it: video analysis and the recommendation engine, a back office for librarians (followed channels, moderation with watched terms and thresholds, usage statistics, feed settings), a mobile web app, and nightly jobs (new arrivals, curated selections, events). Delivered in batches against a written specification.

They say it better than I do: founders who trusted me with their product.

Florian joined my startup as CTO. It changed the whole dynamic! Beyond his technical skills, what I appreciated most was his mindset: with Flo, anything is possible as long as the request makes sense.

When he arrived, he told me: “I'm going to move you from a bicycle to a Lambo.” He did. In three months we changed dimension — a product rebuilt around the real need and the end customer. I recommend him without reservation.

I had the chance to work with Florian on building my CRM platform, and I can only recommend him warmly.

From our very first conversations, Florian understood the specific needs of my business and turned them into clear, effective technical solutions. It's rare to meet a developer who combines that level of technical rigor with genuine listening skills.

Throughout the project he was responsive, reliable and full of ideas. Communication was always smooth, and he delivered a CRM platform that is functional, intuitive and perfectly tailored.

I have the pleasure of working with Florian Argaud on the development of Cocktail Culturel, and I want to highlight the particularly valuable quality of our collaboration.

Florian stands out above all for his seriousness, his reliability and his professional integrity. Meeting deadlines, following instructions and honouring commitments, combined with active listening and great consistency in his work, form a particularly precious foundation of trust.

On the technical side, I especially appreciate his high standards for code quality. He doesn't settle for a working solution: he anticipates side effects, security issues, technological change, maintainability, running costs and display performance. Accessibility and scalability are also among the concerns that make his work so solid.

Florian also has a genuine taste for work well done. He constantly looks for the most relevant solutions, can take on complex technical challenges and brings ideas to the table. The quality of his advice and his ability to clarify technical choices are particularly valuable in an innovative project like Cocktail Culturel, where the problems we face don't always have obvious answers.

Finally, our collaboration is marked by very smooth communication. His agile approach, his responsiveness to bugs, his quick grasp of feedback and his ability to get to the point let us move forward efficiently, without wasting time. This quality of communication is decisive for making rapid progress on developments that carry a large share of uncertainty and innovation.

Florian is a developer you can count on, both for the quality of his work and for the quality of his collaboration. I confidently recommend his work to any organisation or project owner looking for a technical partner who is rigorous, committed, reliable and able to engage in an innovation process for the long term.
