Back to original languageAbout Maxime
Founder of a B2B SaaS (Heeet, multi-touch marketing attribution) deeply integrated with Salesforce and HubSpot, I assist companies with their CRM integration, marketing data architecture, and API connector challenges.
What I can bring to you:
- Development and architecture of Salesforce integrations (API, custom objects, Campaign Influence, AppExchange package)
- CRM ↔ marketing tools connection (HubSpot, Pipedrive, Zoho, Dynamics 365)
- Consulting on marketing attribution and performance measurement (Meta Ads, Google Ads, LinkedIn Ads)
- Backend Node.js/NestJS development for your API and automation needs
- Technical and SEO audit of B2B SaaS platforms
Why choose me:
Unlike a generalist Salesforce developer, I have built and operate a product daily that lives *within* the Salesforce/HubSpot ecosystem – I understand business constraints as well as technical ones: marketing ROI, user adoption, integration scalability.
Available for one-off missions (audits, connector development) or longer-term support (architecture, technical roadmap).
