About Philippe

đź‘‹ I build or accelerate the creation of your MVP!

Hello! My name is Philippe. For over 13 years, I have been designing and developing web applications in small startup teams or solo.

Passionate about product and SaaS, I created and launched Atoly.co alone, the booking system for small service and leisure businesses.

In March 2026, I launched manywalls, this time a mobile app allowing painters to have a museum-worthy portfolio that unfolds like a digital exhibition, with AI protection integrated into the platform.

âś… What I can bring you:

🚀 Creation or acceleration of SaaS products
  • Scalable architecture (monorepo, CI/CD)
  • Full-stack web (TypeScript + Tanstack Start, Next or RR)
  • Mobile Dev (Expo)
  • SQL Database Backend (Cloudflare D1, Turso) or Convex
  • Auth, Stripe/RevenueCat, i18n, emailing, workflows, analytics, SEO…
🎯 Need a reliable and scalable MVP?

Accustomed to going from idea to real product, I build a pragmatic but maintainable MVP. I am aware that creating an MVP must validate an idea with fuzzy boundaries, so I produce malleable but solid code. You hire me to get an MVP that you won't need to rewrite "from-scratch" once product-market fit is found.

🤖I work on your AI-coded MVP or your existing product

I transform your "vibe coded" app into a professional code repository, with CI/CD, tests, I refactor, harmonize practices, and prepare your source code to welcome a development team.

I implement error reporting (Sentry), product analytics (PostHog), and prepare your SaaS launch with usable KPIs to adjust, improve, or convert further.

đź’ˇ Why work with me?

âś” I am autonomous, solution-oriented, and used to business constraints.
âś” Clear communication, transparency on deadlines and priorities.
