About Lucas

Full-Stack Developer | Next.js | SaaS | AI

Launching a SaaS, a business application, or a custom web application? I step in to design a robust product or take over an existing one with a simple requirement: develop a reliable, maintainable application that stays true to the founder's vision.

Some projects:
  • Healance : SaaS platform for audioprosthetists. Managed the complete MVP: product, UX/UI, and development.
  • QRFeedback : SaaS for continuous improvement via instant QR and link feedback. Designed and developed from A to Z, from product scoping to deployment.
  • Initiative Sud : Web tools for an association: personalized mass SMS + event management application with online registration.
What I deliver :
SaaS, business platforms, custom web applications, dashboards, back-offices, APIs, authentication, role management, Stripe integration, and deployment.

I also integrate AI features when they bring real product value : data analysis, automation, user feedback exploitation, and integration of intelligent features into web interfaces.

Stack : Next.js, TypeScript, Prisma, PostgreSQL, Tailwind CSS (T3 Stack).

My approach : beyond development, I act as a technical partner to help structure the project, clarify priorities, and make the right choices at the right time. I place particular importance on the working relationship, teaching, and reliability, in order to build a coherent, clear product aligned with the founder's vision. The goal is to move the project forward with seriousness, flexibility, and high standards, within a framework of trust.
