About Mathieu

Hello,

Lead Full-Stack Developer | From idea to solution

I transform your business needs into tools that truly work.

After several years of developing complex web applications, I've learned one essential thing: code is just a means. What matters is understanding your business, your constraints, and building a solution that integrates naturally into your daily life.

My approach I don't just execute a specifications document. I question, I propose, I challenge — so that the final product exceeds your initial expectations. I also integrate AI where it brings real added value to your processes.

What I develop → Custom business applications & ERPs → SaaS platforms → E-commerce sites → Web apps & PWAs
