Valentin F.

Do you have a SaaS idea, a web platform, or a business tool that you want to see come to life, not in 6 months after a €30k agency fee, but in the coming weeks? That's precisely where I come in.

I am an independent fullstack developer specializing in the design and delivery of complete SaaS MVPs, from backend to deployment. Modern stack (Next.js, React, Node.js, MongoDB), out-of-the-box integrations (Stripe, OAuth, AWS S3), responsive cross-device design, and architecture built to scale when your traction justifies it.

My background is atypical: trained in language sciences and formerly an independent international trainer for over 3 years, I pivoted to development by building Frenship myself, an edtech learning platform sold to real paying users. This dual product + tech expertise allows me to understand your business challenges before writing the first line of code.

What I deliver concretely:

• Complete SaaS MVPs in 3 to 6 weeks

• Payment integrations (Stripe), multi-provider authentication (Google OAuth, email), cloud infrastructure (AWS, Vercel)

• Turnkey responsive web platforms

• Taking over and finalizing projects started in no-code or via AI (Lovable, Cursor, Bolt, v0) that got stuck halfway

• Mini-games and interactive experiences in Phaser for edtech or marketing needs

If you're looking for a dev who delivers quickly, understands your product as much as your code, and doesn't disappear after the final commit, let's talk.
