About Louis

Fullstack developer and Tech Lead, I support SMEs, freelancers, and product teams in the design, redesign, and maintenance of their websites and web applications.
In 6 years, I have worked in startups, health media, fintech, and consulting, as well as independently, which allows me to quickly understand your challenges: budget, deadlines, compliance, reporting.

- My playground:

Showcase websites and business mini-apps in Next.js / React / Node.js
B2B landing pages focused on leads (forms, appointments, registration funnel)
Technical SEO and quality (W3C, Lighthouse, RGAA accessibility, GDPR cookie management)
CI/CD, deployments, and observability (GitLab, Debian, Vercel, OVH, Hetzner VPS)
AI integration and automations (prospecting, emailing, internal tools)

- What I bring to the table:

Fullstack JavaScript/TypeScript (REST API, PostgreSQL, MongoDB)
DevOps & quality: CI/CD pipelines, monitoring, security, GDPR
Compliance & accessibility: RGAA audits, accessibility statements, CNIL-compliant cookie banners, ARIA attributes, keyboard navigation
"AI Swiss Army Knife": Claude / OpenAI / Perplexity agents, n8n workflows, personalized message generation, tooling for your non-technical teams
Recent examples: ConfRoomOwner CRM (strong authentication, billing, marketplace connectors), ARX CRM (prospecting + AI automations), showcase websites and editorial pages for 1Health, Au Paradis O'Fer, and Lelly Mosaïque

I can take a project end-to-end - from scoping to production - while remaining clear for non-technical decision-makers. Let's discuss your project.
