Freelancer profile translated to English.

Description

For 16 years, I have been designing and developing custom SaaS applications and ERPs—from the first line of code to production deployment. I am as comfortable building a product from scratch as I am taking over an existing, struggling system and putting it back on solid rails.

My playground: Laravel, Vue.js, Nuxt, Tailwind CSS.

I master this stack end-to-end—backend architecture, APIs, reactive interfaces, testing, CI/CD, deployment.

→ -90% time-to-market.

🔧What I bring to your project

**SaaS & ERP Construction**: I translate your business needs into software architecture, develop features, and implement testing and CI/CD. You get a robust, documented, and maintainable product.

**Modernization & Migration**: I audit your existing system, define a progressive roadmap, and migrate your application to a modern architecture—without production interruption.

**Compliance & Business Tools**: electronic invoicing (Factur-X), eco-contribution (AGEC), regulatory middlewares—I know how to integrate these constraints into your existing workflows.
