Back to original languageAbout Damien
Full-stack developer with 4 years of experience, I design and evolve modern web applications.
My core business: React.js, Next.js on the front-end, and NestJS / Node.js on the back-end, with PostgreSQL as the database. I have worked on concrete projects with high impact.
On a daily basis, I am involved in:
- Designing and evolving features — from mockups to deployment, with a real culture of UX detail
- Front-end architecture — design systems, Storybook components, long-term maintainability
- Data and state management — TanStack Query, optimized CRUD, fluid front-end/back-end synchronization
- Code quality — demanding reviews, clear documentation, targeted tests
I integrate naturally into agile teams (GitLab, Jira) and am comfortable working remotely as well as on-site.
Available quickly, for short missions as well as long-term engagements. I respond within 24 hours. Share your needs with me, and we'll find the best way to move forward together.
