About me

I’m Lionel, a full-stack developer whose journey into computer science started during my three years of high school, where I first learned to turn ideas into interactive projects using Scratch. That first taste of building with code made me hungry to explore what else was possible.

From there I kept pushing into new tech stacks and tools, and during my IMS training I joined the first Baden Hackathon, where a friend and I built my first end-to-end application in a single run. Since then I’ve shipped projects both with him and on my own, learning as much from the failures as from the things that worked — experience is power.

Today I’m channelling that same curiosity into a sophisticated AI project for contract analysis while also building my own SaaS products. My work spans the entire stack — from designing databases in Supabase to crafting pixel-perfect frontends in Next.js.
