About Uwa

If your team still runs on spreadsheets, disconnected tools,
or a product that needs to be built properly, that is the
work I do.

I design and ship full-stack web applications in Next.js,
TypeScript, Supabase, and PostgreSQL, from schema design
through to live deployment.

Recent projects: a consular portal in Paris with an applicant
portal and internal staff dashboard for passport processing,
and TraviXO, a live multi-tenant SaaS for VGP compliance in
equipment rental.

Based in the Paris region. Bilingual FR/EN. Available for
short or long-term contracts in France and internationally.


Vous avez des processus manuels, des outils qui ne se parlent
pas, ou un produit SaaS à construire from scratch. C'est là
que j'interviens.

Je conçois et livre des applications web full-stack en Next.js,
TypeScript, Supabase et PostgreSQL, du schéma de base de
données jusqu'au déploiement en production.

Deux projets récents : un portail consulaire à Paris avec
espace candidat et tableau de bord agent pour le traitement
des demandes de passeport, et TraviXO, une plateforme SaaS
multi-tenant pour la conformité VGP dans la location de
matériel, en production.

Basé en Île-de-France, bilingue FR/EN, disponible pour des
missions courtes ou longues en France et à l'international.

Experience

  • Deralis Digital SAS,
    Full-Stack Developer
    January 2026 - Today (6 months)
    Île-de-France, France
    Deralis Digital is my independent engineering practice. I build full-stack web systems and B2B SaaS products for businesses. My work includes internal tools, client portals, and operations platforms that replace spreadsheets and manual workflows.

    Stack: Next.js 14+ (App Router), TypeScript, Supabase (Postgres, Auth, Storage), Vercel, Stripe, Tailwind. I design multi-tenant architectures with row-level security and role-based access control. I also ensure clean data integrity patterns from the database up.

    Current focus:TraviXO Systems, a multi-tenant SaaS for VGP compliance tracking targeting French equipment rental companies. I built it from start to finish, including the schema, authentication, billing, and deployment.

    I also develop internal AI tools for my own delivery pipeline. I create custom GPTs for client scoping, use Python and ReportLab for automated proposal generation, and build Claude-based workflows that reduce build time on client projects.

    Approach: I validate ideas before building. I ship clean, documented code and hand over systems that clients can easily maintain.
