À propos de Quentin

Available from August 1, 2026

Tech Lead & Architect · Mission-Critical SaaS · Fintech & Healthcare

With over 8 years of experience in Luxembourg's highly regulated sectors, I architect, build, and secure complex SaaS platforms from infrastructure to frontend. Acting as Tech Lead and sole architect on multiple projects, I specialize in delivering robust systems where security, compliance, and reliability are non-negotiable.

Expertise & Track Record:

  • Healthcare (MedTech): Full integration with Luxembourg's national health systems (CNS PID V2, CNS ECIT, LuxTrust) and ophthalmic medical devices (Node.js).
  • Finance (Fintech): Architecture of white-label SaaS platforms and API gateways for major Benelux banks (Belfius, BNP Paribas Fortis, Cofidis, Elantis).
  • Security & DevOps: Defensive pentesting (patching RCE, IDOR, XSS), CI/CD pipelines setup (GitHub Actions), and AI-assisted workflow integration (Claude Code).
Core Tech Stack:
PHP • Laravel • TypeScript • Node.js • React • Vue.js • MariaDB/PostgreSQL • REST APIs / OAuth2.

Availability:
Available for Hybrid or On-site missions in Luxembourg and Belgium.
