Ferhat Saidoun

Full‑Stack & DevOps Software Engineer

I build TypeScript web applications and the platforms that run them: Kubernetes, GitOps, hardened CI, highly available databases.

See the projects Get in touch
Diagram of how I ship: every change starts with a git push, goes through tests and the Trivy security scan, becomes an image and is deployed by Argo CD to a highly available Kubernetes cluster (GitOps, encrypted secrets, continuous backups, automatic TLS, SSO), then reaches production through a rolling update.

From code to cluster, end to end.

Software engineer graduated from ENSSAT, with more than four years of experience across an internship, a work-study programme and a permanent role. Today a full-stack engineer at Cronexia in Paris, I build TypeScript applications, from NestJS backends to SvelteKit interfaces.

On the platform side, I design and run Kubernetes infrastructure the GitOps way: replicated databases, backups and a hardened CI/CD pipeline. This double perspective, development and operations, shapes how I build: readable, tested code, shipped continuously and secure by default.

  • Development

    NestJS APIs, SvelteKit interfaces, end-to-end TypeScript, automated tests.

  • Platform

    Kubernetes the GitOps way with Argo CD, highly available PostgreSQL, continuous backups.

  • Security

    Keycloak SSO, hardened CI (Trivy, pinned dependencies), secrets encrypted with SOPS.

Between product and infrastructure.

Internship, work-study, then a permanent role: from secure intranets to modern web platforms.
