Are you building a proptech product or SaaS from scratch and looking for aweb developerwho can take you to scale, not just to the mockup?
Your platform deserves a SaaS developer who takes it from idea to scale, not just a front-end integrator. I design your product from architecture to production: full-stackReact.js/Next.jsin TypeScript, custom APIs, and Laravel when your project requires it.
And when you want a realartificial intelligencecomponent in your SaaS, I design and code it myself — AI agent, generative AI, RAG assistant that cites its sources — rather than outsourcing it.
Here are some concrete results to help you visualize:
SuperHote (Rental Management SaaS): Complete rebuild of V2 in React.js / TypeScript / Laravel, a platform that now manages100,000+ hosts and concierges**, **€274M in revenue generated**, and **15 hours saved per weekper user.
Real Estate Agency: Web application for property valuation connected via API to over 400 Parisian property sales — your agents estimate a property based on comparable real transactions, not an approximate figure.
Crédit Agricole Centre France: Overhaul of the institutional website and internal tools for a large banking group — reliability, security, and performance were required.
You work directly, without agency outsourcing. You state your business objective, I build your custom data-driven platform, with AIautomationif needed. The preferred field remains proptech, but the same logic applies to any B2B SaaS editor that wants a solid **SaaS MVP**.
Have a product in mind? Describe your project in 3 lines, and I'll respond within the hour with an initial analysis.
