Back to original languageAbout Quentin
Freelance WordPress developer based in Tours. 10+ years of experience in website creation, WordPress maintenance, and custom web development.
I work with VSEs, SMEs, and startups on four types of missions.
WORDPRESS WEBSITE CREATION AND REDESIGN
Showcase websites, WooCommerce e-commerce sites, custom sites.
Each site is built for your business: optimized performance, technical SEO integrated from the design phase, mobile responsive.
I maintain WordPress sites in production daily – I build differently because I know what breaks after 6 months.
3 months of technical support included after delivery.
WORDPRESS / WOOCOMMERCE AUDIT AND MAINTENANCE
Your site is slow, vulnerable, or obsolete.
I identify vulnerabilities (security, performance, technical SEO, GDPR compliance) and fix them.
Typical result: loading time divided by 3, PageSpeed score from 30 to 85+, critical vulnerabilities removed.
Monthly preventive maintenance: updates, monitoring, backups, SSL and headers surveillance.
CUSTOM WEB MVPS AND APPLICATIONS
Need an internal tool, a dashboard, a landing page, or a SaaS?
I develop in Next.js, TypeScript, React. From functional scoping to delivery, in short iterations.
AUTOMATION AND DATA
Scraping, enrichment via API, Python pipelines, automated scoring, AI integration.
Complete prospecting pipeline built and deployed in production.
Each mission starts with written scoping: scope, deliverables, deadlines, price. No surprises.
Out of scope: pure web design, SEA, native mobile applications.

Delighted with this first collaboration with Quentin.
We had a bug on our WordPress site after a PHP and child theme update that he resolved.
I had already asked a webmaster but they hadn't managed to debug it.
Quentin did.
Our site is working correctly again.
Also noteworthy is the perfect support until the end, especially to help us regain control of site updates.
