Back to original languageAbout Guerric
I am a Web Developer specialized (and certified) in HubSpot (CMS + CRM)
I support marketing, growth, and RevOps teams in the creation and optimization of websites, landing pages, and automations.
Objective: accelerate go-live, improve conversion, and streamline the customer experience.
My clients' challenges
• Websites or LPs difficult to update → slowed campaigns
• External website to HubSpot → underutilized CRM, declining conversion
• Insufficient performance & SEO
• Digital identity to modernize or standardize
• Too many manual tasks → errors + wasted time
• Poorly segmented workflows → poorly qualified leads
• Insufficient post-form follow-up → forgotten prospects
My HubSpot expertise
Content Hub / HubSpot CMS:
• Creation / redesign / migration of complete websites
• Conversion-oriented landing pages
• Addition of pages, modules, or templates to an existing theme
• Creation of email and quote templates
Automation & CRM integrations:
• Workflows (nurturing, scoring, follow-ups…)
• API connections & business automations
My background
I attended business school and then worked for several years in finance.
Result: a business-first perspective on projects.
I then joined Markentive, the leading HubSpot agency in Europe (Top 5 globally), where I:
• Collaborated closely with RevOps and Growth teams
• Worked for clients such as Legalstart, Fondation Louis Vuitton, Piguet Galland…
• Developed scalable, performance-oriented HubSpot websites
• Structured projects with clear, collaborative, and documented management
This mix of Business + Marketing + Tech allows me today to help teams move fast without sacrificing strategy.

HubSpot Module CreationBANKING AND INSURANCEDecember 2025 - December 2025As part of this project, I designed and developed a library of HubSpot CMS modules dedicated to landing pages, fully aligned with the existing graphic charter.The objective was twofold:👉 respect the overall design of the site,👉 give maximum autonomy to the marketing teams.I developed several key modules (hero, text & media sections, cards, animated key figures, testimonials, sliders, etc.) going beyond simple integration. Each module was designed as a reusable and adaptable block, with numerous customization options directly from the HubSpot editor:- layout variations (block order, conditional display),- fine-grained CTA management (number, style, colors),- animations (especially on key figures),- advanced visual settings (backgrounds, images, rounded corners, colors).I also proposed functional and UX improvements so that each module could adapt to a maximum of use cases, without requiring new developments. - Piguet GallandCreation of 130 Custom Pages on HubSpot for Piguet GallandBANKING AND INSURANCESeptember 2025 - October 2025 (1 month)As part of a major project for the bank Piguet Galland, I designed and developed 130 HubSpot pages (mostly landing pages), directly integrated into their client application.Each page was fully personalized by persona:
- dynamic adaptation of texts, amounts, and scenarios,
- possibility for the user to modify their own data to obtain tailor-made results,
- optimization of conversion & performance on HubSpot CMS,
- industrialization of the process for rapid large-scale deployment.
Result: a high-value customer experience, fully personalized, and a perfectly maintainable system for internal teams.
