Back to original languageAbout Erwan
Hello, I am Erwan Manchec, a WordPress & WooCommerce developer since 2009.
For over 15 years, I have been assisting companies with their web projects: showcase sites, e-commerce, intranets, and SaaS tools.
🎯 My priority: to create fast, secure, and scalable websites designed to last.
🚀 Showcase & E-commerce Website Creation
I design custom WordPress sites from your mockups (Figma, etc.) or directly based on your needs.
I use Bricks Builder, Elementor, or Oxygen to ensure faithful rendering, clean and maintainable code, and optimal performance from launch.
⚙️ Performance & Optimization
Each project relies on lightweight, scalable code with a performance-oriented architecture for fast, stable, and durable websites.
I also work on existing sites to improve their performance.
🧩 WordPress Maintenance
I offer regular monitoring of your site: secure updates, automatic backups, performance monitoring, and quick fixes to ensure a stable, safe, and always up-to-date website.
🧠WordPress Site Migration
I handle the complete migration of your site, ensuring a smooth transition with no downtime or data loss, and performance monitoring after launch.
🔍 SEO & User Experience
Technical optimization, semantic structure, Core Web Vitals, Rank Math / SeoPress / Yoast, and navigation improvements for a smooth experience on all devices.
🤖 Automation & AI
I integrate automation solutions (n8n, Make, API) and artificial intelligence to simplify your processes: data synchronization, content generation, intelligent email sending, or connection with your business tools.
With 15 years of experience, I support my clients in all aspects of their web projects: development, performance, security, and maintenance, with clear code and real responsiveness.

I have been working with Erwan for 6 years now, and he has become much more than just a service provider: a true trusted collaborator.
He manages all the WordPress and server aspects with seriousness, responsiveness, and always provides good solutions when there's a problem or an evolution to implement.
What I particularly appreciate is that you can ask him a lot of questions, easily discuss technical subjects, and he always takes the time to explain things clearly.
Reliable, available, and involved in the long term, which is quite rare.
I highly recommend Erwan to anyone looking for someone competent and pleasant to work with đź‘Ť

The WordPress and WooCommerce ecosystem can quickly become a minefield with server configurations, structuring technical choices, and a profusion of more or less reliable plugins. After the very costly failure of an agency on our e-commerce site redesign, we called upon Erwan, and it was a decisive turning point. From hosting to technical WordPress choices (plugins, etc.), including SEO and performance decisions, Erwan has been an exemplary partner. He manages to combine modernity, pragmatism, and agility, which is truly rare in this ecosystem.
Erwan now handles the complete maintenance of our site, from the server to the plugins, with a proactive approach to security and stability. He is also extremely available in emergencies. Whether it's a PayPal hack or critical issues arising in production, he always responds and provides concrete help to move forward quickly and effectively. I recommend Erwan to any company that truly wants to level up its WooCommerce site and sleep soundly.
