Back to original languageAbout Antoine
I build web apps. And I audit them too.
Next.js full-stack dev, I designed and deployed Sitoscope.fr alone — a SaaS that audits sites on 107 criteria: performance, accessibility (RGAA), SEO, security. BullMQ/Redis pipeline, Playwright, Lighthouse, axe-core, reports generated via Claude API.
From frontend to VPS infra, it's all me.
What this means for your project: I code knowing exactly what an audit will reveal. Performance, accessibility, and security are built-in from the start, not tacked on at the end.
My services:
— Complete development of Next.js / TypeScript web apps
— High-performance e-commerce sites and portfolios
— Technical audits of existing sites (performance, accessibility, SEO)
— Refactoring of codebases with technical debt
— Preparation for the European Accessibility Act (RGAA)
effective June 2025
My added value: I'm training to be a systems/networks/cybersecurity administrator — a useful perspective for sensitive projects or critical infrastructure.
Contact me if:
— you want a product delivered by the person who codes it, with no intermediaries
— your site is slow and you want to understand why before rewriting everything
— you're preparing for an accessibility audit or want to anticipate the European Act
