- General Manager & CTO of 10Nord, I align business, product, and technology strategy to deliver robust, secure, and profitable platforms. I operate in demanding environments (e-health, pharmaceutical retail, B2B SaaS) with a results-oriented approach: reduced time-to-market, measurable software quality, controlled costs, and security by design.
- My playground: application redesigns and IT system modernization. I design API-first, modular, scalable architectures, leveraging Next.js 15 / TypeScript, Prisma, Postgres/PostGIS, and an industrialized DevOps stack (Docker, Kubernetes, Nginx). I implement CI/CD pipelines (GitHub Actions, GitLab CI), useful observability (logs, metrics, traces), and clean SSO (OIDC/SAML) to simplify access and strengthen governance.
- On the product side, I structure the roadmap with clear OKRs, manage discovery/delivery, secure MVP scoping, and establish rituals that streamline collaboration between CEO, sales, and technical teams. My mantra: regular shipping, fast feedback, controlled technical debt. Simple, typed, tested (ESLint/Biome) and documented code to accelerate onboarding and maintainability.
- Examples of typical impacts: Next.js redesign that halves time-to-market, CI/CD pipeline implementation that reduces incidents and speeds up go-to-market, contained and reversible cloud migration, Postgres/BI data stack that informs decisions (usage, performance, costs).
