Hello, I'm Armand. I build robust software systems and high-performance web applications. Specializing in reactive architectures and DevOps culture, I also co-founded and lead Voxel Studio, a 7-member association where I coordinate the development of modular collaborative software.

My approach combines backend robustness (secure APIs, Docker, automated CI/CD) and fluid, optimized frontend interfaces. Passionate about GitOps automation and Zero-Trust architectures.

> Portfolio, interactive cockpit

// FORMAT: LIVE SYSTEM

This site is the project: an interactive Nuxt 4 cockpit that I designed, built and run myself, from the code to the deployment on my VPS. Rather than describe good practices, I run them in production all around you.

Security
Strict nonce-based CSP, server-signed challenge, isolated socket-proxy network, dependency audit in CI.
Quality & delivery
Vitest and Playwright tests, typecheck in CI, HMAC webhook deployment, multilingual SSR prerendering.
Real time
Simulations in a Web Worker, event bus feeding the Overseer AI, multi-API audio player.

// The proof is all around you

Hover a marker: the module lights up in the cockpit.

[01] Starting point

Before engineering school, I set out to build a Zero-Knowledge messenger on my own: the server was meant to be nothing more than a blind relay. This is the project that got me into security.

[02] What the July 2026 audit revealed

The July 2026 audit found 9 major flaws, including:

  • FLAW 01 • SECURITYRSA private key in clear in localStorage
  • FLAW 02 • PERFORMANCEpbkdf2Sync blocks the Node.js event loop
  • FLAW 03 • NETWORKHTTP session revalidation every 30 s
  • FLAW 07 • COMPLIANCEOver-provisioned Android permissions

What it triggered: the CCNA certification, the hardening of this portfolio and the CVE watch built into the site.

    Dark Patterns, cognitive dissonance & security decisions

    • Context Academic research project carried out alone in spring 2026, as part of the UTBM MR52 module.
    • What was done Design, administration (n = 78) and analysis of a 2×2 factorial experiment exploring the influence of Dark Patterns and induced hypocrisy on security decisions.
    • Result In the sample, the submission rate goes from 5.6% to 26.3% with the Dark Pattern: a trend that needs confirming on a larger sample.
