Back to original languageAbout Kévin
Hello 👋
For over 10 years, I've been helping startups, scale-ups, and companies design and deliver high-performing web products. My goal: transform your ideas into reliable, fast, and user-friendly applications — on time, without accumulating technical debt.
🛠️ My technical expertise:
∙ Front — React, Next.js, Tanstack Start
∙ Back — NestJS, Node.js, tRPC, GraphQL, REST
∙ Tests — Vitest, Jest, Cypress, Puppeteer
∙ CI/CD — GitLab CI, GitHub Actions
∙ Cloud & Infra — AWS, Scaleway, OVH, Scalingo, Terraform
∙ Data & Perf — Redis, S3, CDN, WebSockets & Monitoring
But what really matters is what's produced beyond the code:
∙ ✅ Predictable deliveries, without unpleasant surprises
∙ 🏗️ Code that lasts, without accumulating technical debt
∙ 👥 Teams that don't suffer from technical legacy
🎨 From Figma mockups to production, frictionlessly. I translate your designs into pixel-perfect interfaces, with a constant focus on accessibility (RGAA). A well-made product is a product usable by all your users 😁
🧭 A trusted technical contact, not just an executor. I simplify complex topics, challenge specs when necessary, and warn you early if a choice is likely to cost you dearly later.
Are you taking over an existing project or have doubts about your current technical choices? I also offer audits to identify friction points and areas for improvement — with concrete and actionable recommendations.
🤝 I work transparently, with clear communication on progress, technical choices, and any potential risks — so you're never in the dark about your own project.
So, if you have a project to launch or an existing application to evolve, contact me. I respond quickly, and we can align on your needs together from the first conversation. 💬
