About Romain

Full-stack developer and technical SEO consultant, I help businesses and e-commerce sites achieve high-performing websites that generate qualified traffic and convert effectively.

Specifically, I can assist you with:

- Technical SEO: comprehensive audits, search intent analysis, continuous monitoring and optimization, crawl structure, Core Web Vitals, Google Search Console indexing
- Custom web application development (Laravel, Vue.js): business platforms, secure payment systems, complex integrations
- WordPress site creation and redesign (Bedrock/Sage stack), designed from the outset for performance and SEO

What sets me apart: I don't just code or audit occasionally; I understand the business challenges behind each project. My dual developer/SEO profile allows me to build technically sound AND well-referenced sites, with ongoing support if needed, without requiring multiple providers.

Typical projects: SEO support (audit + monthly monitoring), Laravel application development, WordPress redesigns, payment system implementation (Stripe), custom automation and tools.
