## Featured Projects

### 1. Organ - Collaborative Management Platform
- **Role**: Co-creator & Lead Developer (in partnership with Voxel Studio association)
- **Architecture**: Polyglot persistence pairing MySQL (Doctrine ORM) and MongoDB (Doctrine ODM + GridFS). Nightly aggregation pipelines, Server-Sent Events (Mercure Hub), Angular Web app & Native Android Kotlin app (Jetpack Compose, MVVM).

### 2. Privy - End-to-End Encrypted Messaging
- **Role**: Lead Developer
- **Architecture**: Zero-Knowledge encrypted messaging platform featuring client-side cryptographic key derivation, instant WebSocket/SSE relay, and ephemeral payload destruction.

### 3. FUI Cyberpunk Portfolio Website
- **Role**: Creator & System Architect
- **Architecture**: Built on Nuxt 4 SSR with futuristic FUI (Futuristic User Interface) design inspired by Cyberpunk 2077. Features an interactive UML system topology canvas (`/architecture`), continuous CVE vulnerability feeds, real-time audio metadata synchronization, and NVIDIA NIM LLM AI integration ("Overseer AI").

## System Architecture Summary
Public requests are proxied by Cloudflare WAF/CDN to a hardened Linux VPS host running Nginx on TLS 1.3 (port 443). Nginx reverse-proxies to a non-root Docker container running Nuxt 4 Nitro (port 3000). CI/CD updates pass through GitHub Actions -> GHCR registry -> HMAC-SHA256 signed Webhook -> Zero-Trust IPC file flag -> Autonomous Deployer daemon with 10-second healthcheck auto-rollback.
