Custom web application development in France
You have a web app idea but don't know where to start? I handle development end-to-end: architecture, backend, frontend, deployment and maintenance. Modern stack, clean code, fast delivery.
What type of application?
- SaaS: subscription, authentication, dashboard, billing
- Marketplace or B2B platform
- Internal tool (management system, process automation)
- MVP to validate your idea before hiring a team
- REST or GraphQL API for your mobile app
Tech stack
→Frontend: Next.js 15 (App Router, SSR/SSG, native SEO)→Backend: Python 3.12 + FastAPI — fast, typed, auto-documented→Database: PostgreSQL 16 — reliable, scalable→Auth: NextAuth.js or Supabase Auth→Deployment: CI/CD GitHub Actions → AWS or VPS→Testing: Pytest (backend) + Playwright (e2e)
From idea to production
- 1Scoping: we define priority features together (MVP first)
- 2Architecture: documented technical choices, no hidden debt
- 3Iterative development: regular deliveries, fast feedback
- 4Production launch: CI/CD, monitoring, technical documentation
Frequently asked questions
- How long does it take to build a web application?
- An MVP (core features) is typically delivered in 6 to 10 weeks. A more complex application takes 3 to 6 months. I deliver in iterations so you have something working quickly.
- Can I take over the codebase after delivery?
- Absolutely. The code is clean, documented, and hosted in your own Git repository. I can train your technical team or handle maintenance if you prefer.
- Do you use cutting-edge or battle-tested technologies?
- Both. Next.js, FastAPI and PostgreSQL are mature technologies with large communities. I don't use experimental libraries in production.
