Allan Lessort
Fullstack Software Engineer
Back-end software engineer (PHP / Symfony) with 3 years on a high-volume B2B SaaS platform, complemented by React on the front. I design and ship features end-to-end — from data model to UI.
I started in graphic design and became an engineer: a path that gives me both an eye for user experience and back-end rigor. Comfortable across the whole cycle — design, build, deploy, maintain.
