Back to original languageAbout Sebastien
I am a Fullstack developer specializing in Angular & NestJS, passionate about creating performant and accessible web applications.
My approach: designing maintainable and inclusive interfaces (WCAG) on the front-end, and robust, well-structured APIs on the back-end from end to end, without compromising on quality.
What I bring:
Clean and reusable Angular components
Scalable NestJS APIs with Drizzle ORM & NeonDB
Particular attention to accessibility and user experience
A modern stack in production with Docker & Dokploy
Whether it's starting a project from scratch or evolving an existing app, I like to understand business needs to deliver solutions that last.
