About Jérémy

Fullstack developer and automation expert with over 6 years of experience, I am co-founder of Fragments Studio, a Parisian agency specializing in web, mobile, and AI integration development. At Fragments Studio, we support our clients with genuine human connection! A single point of contact, direct communication, and long-term support. My area of expertise is connecting your tools, automating your repetitive processes, and integrating AI where it creates real value for your team.

What you gain by working with me:
  • **Hours saved every week**: identify time-consuming tasks you do manually — I automate them so your team can focus on what's essential
  • **Zero disruption to your existing tools**: I speak the language of the tools you already use (CRM, ERP, Slack, Notion, GSuite...) and connect them without rebuilding everything
  • **Automations that last**: your workflows are documented, maintainable, and adapted to your technical level
  • **A team behind you, not just an automator**: through Fragments Studio, you also access fullstack, AI, design, and mobile development skills if the project evolves

What I do:
  • Design and deployment of automated workflows (n8n, Make, Zapier)
  • Integration of AI into your processes: automatic summaries, classification, content generation
  • Development of MCP servers to connect business systems to AI agents
  • Connection of third-party tools: CRM, ERP, Slack, Notion, Google Workspace, Airtable...
  • AI Productivity: implementation of internal assistants, prompt engineering, custom tools
  • Fullstack React / NestJS development for complementary needs
