About Quentin

I help companies transform their business processes into high-performing digital tools: automation, AI, dashboards, CRM, ATS, recruitment workflows, client acquisition, and SaaS MVPs.

My profile is hybrid: JavaScript full-stack developer, IT recruiter, SaaS entrepreneur, and automation consultant.

I am involved in scoping, product design, development, and process optimization.

My preferred topics:

- Development of internal tools and SaaS MVPs
- Automation of business workflows
- Integration of AI into existing processes
- Creation of ATS, CRM, dashboards, and steering tools
- Automation of prospecting, sourcing, and candidate tracking
- Redesign or improvement of existing web applications
- Product, UX, and technical architecture consulting

Main Stack:

Next.js, React, Vue.js, Node.js, TypeScript, Supabase, PostgreSQL, API, Stripe, n8n, OpenAI, Claude.

I don't just develop a feature: I seek to understand the real business problem, propose a simple solution, and then deliver it effectively.

I am capable of creating a product from A to Z, from ideation to market launch.
