About Geoffrey

Hello 🙂

► Are you a startup, an Agency (advertising, web, SEO, 360…), a business, an association?

► Do you need:
- to create a website from scratch?
- a one-off intervention on one of your existing structures?
- to strengthen your team on a particular project?
- to subcontract white-labeling for an exceptional workload?

✅ With experience in various types of structures (startups, SEO agencies, 360 agencies), I have been developing and maintaining websites with passion for over 10 years.

► My expertise extends to the following areas and technologies:
- Extensive knowledge of the WordPress ecosystem, theme and plugin creation
- eCommerce issues: Prestashop, WooCommerce, payment gateways, CRM and cash register software connectors…
- Custom platforms (SAAS) or APIs under Symfony
- Creation of graphic charters (WebDesign, UX…)
- Web Referencing Services: SEO Audits, internal optimization (onsite)…
- Implementation of API solutions: Google AMP, Analytics, Tag Manager,
- Development of specific tools: Scrapers, growth hacking…

► Why use my services ❓
Seeking to build a lasting relationship of trust with my clients, I guarantee you:
- Precise and detailed scoping before any service
- Production combining aesthetics, efficiency, and security
- Fluid communication and transparency throughout the project
- Adherence to announced deadlines
- Care taken with the quality of the code produced (adherence to development standards)
- Systematic consideration of referencing issues (SEO)

► My services can be provided in person in Lyon or in the Haut-Rhin department.
I also work remotely with clients throughout France.

See you soon!
