About Brice

Looking for a freelancer to develop or modernize your web app/site in React / Next.js? You've come to the right place.

⚛️ Front-end & Fullstack JS Web Developer (React, Next.js, Node.js)
🌐 Showcase websites, business apps, dashboards, PWAs
🚀 Deployment (Vercel / AWS), performance, and technical SEO
📁 Several real projects delivered for freelancers and SMEs

The problem?
Slow sites, not mobile-friendly, total dependence on the previous developer, outdated stack… Result: dated image, loss of credibility and leads.

I provide product development services: I start from your business needs and deliver a clean, maintainable product online.

Here's what I'll set up for you:
1 - Quick scoping: business, objectives, priorities
2 - Action plan: features, tech stack, clear timeline
3 - Iterative development: accessible pre-production, frequent feedback
4 - Go-live: domain, environment, analytics
5 - Stabilization + handover: final fixes, brief documentation, handover

Why trust me?
✅ Modern stack: React, Next.js 13/14, TypeScript, Tailwind, Node.js
✅ Structured, typed code, versioned on Git
✅ Patient with non-tech clients, direct communication
✅ Reliable and responsive

Indicative daily rate: from €350/day (fixed price possible for showcase sites / small apps).
