Freelancer profile translated to English.
Back to original languageAbout Vincent
I build software products end-to-end, with a pragmatic, impact-oriented approach.
With over 10 years of experience in Ruby on Rails development, I take charge of an entire project: understanding the need, product design, technical implementation, and deployment. My goal is simple: deliver useful, reliable, and sustainable solutions.
Comfortable with both technical and product topics, I work at the interface of teams and businesses to transform sometimes vague ideas into concrete and well-executed features.
My work environment, heavily assisted by AI, allows me to develop complete projects more efficiently while maintaining a high standard of code quality, maintainability, and security.
I have contributed to fintech and SaaS products with millions of users, I maintain open-source projects, and I regularly share my learnings at conferences and on my blog.
