Profile & Academic Background ### Biography & Vision URL: https://alexmaina.dev/about/ - **Full Name:** Alessandro Mainardi - **Role:** Software Developer & Computer Engineering Student - **Institution:** Alma Mater Studiorum - Università di Bologna (UniBo) - **Degree Course:** Ingegneria Informatica (Computer Science and Engineering) - **Primary Technical Focus:** - Cloud Architecture: Microsoft 365, Microsoft Entra ID, Microsoft Azure, Intune Endpoint Management. - Systems & Infrastructure: Windows Server 2025, Hyper-V, Linux (Debian/Ubuntu), Docker containerization, Zero-Trust network topologies (Tailscale, Cloudflare Tunnel). - Storage & Resilience: Storage Spaces with ReFS (Resilient File System), Veeam 3-2-1 backup strategy. - Software Engineering: TypeScript, React, Next.js (App Router), Python, PHP, C, SQL (SQLite, MySQL), RESTful APIs. ### Engineering Philosophy Alessandro focuses on sovereign, resilient, and zero-compromise systems: - **Zero-Trust Network Access:** Elimination of exposed public WAN ports via mesh VPNs (Tailscale WireGuard) and encrypted application proxies (Cloudflare Tunnels). - **Data Sovereignty & Redundancy:** Hybrid setups combining cloud management with local hardware ownership, automated scheduled backups, and self-healing filesystems. - **Modern Clean Code:** Semantic HTML, type-safe development with TypeScript, automated CI/CD pipelines, and rigorous automated testing. --- ## 2. Featured Projects & Architectures ### HP Fortress Homelab — 24/7 Enterprise Server Infrastructure URL: https://alexmaina.dev/hp-fortress-homelab/ Repository: https://github.com/AlexMaina05/hp-fortress-homelab Infrastruttura server enterprise ibrida on-premise basata su hardware enterprise HP ProLiant ricondizionato, progettata per simulare e implementare standard di produzione data center reali. #### Architettura a 3 Livelli (3-Tier Topology) 1. **Tier 1: Ingress & Zero-Trust Security** - Cloudflare Tunnel: Outbound-only tunnel delivering TLS termination at the edge without opening any inbound ports on the WAN gateway (Zero WAN open ports). - Tailscale Mesh VPN: Encrypted peer-to-peer WireGuard mesh network for administrative control, remote terminal access, and monitoring. 2. **Tier 2: Compute & Hypervisor** - Windows Server 2025 Host with Intel Xeon enterprise CPU and ECC memory. - Hyper-V Hypervisor for hardware-isolated workloads. - Docker Engine orchestrating lightweight microservices (Plex, Navidrome, reverse proxies, and internal web applications). 3. **Tier 3: Storage & Disaster Recovery** - Storage Spaces con file system ReFS (Resilient File System) dotato di integrità dei flussi dati e auto-healing contro il bit-rot. - Disaster Recovery 3-2-1: Snapshot locali periodici, backup locale cifrato su NAS e replica cloud off-site cifrata tramite Veeam Backup & Replication. --- ### Officina Control Tower (`auto-se`) Repository: https://github.com/AlexMaina05/auto-se Applicazione web gestionale monolitica a basso consumo di risorse per il tracciamento dei flussi di riparazione in officina, approntamento consegne veicoli nuovi e gestione flotte con codifica cromatica personalizzata. #### Stack Tecnologico - **Framework:** Next.js 15 (App Router) + React 19 - **Linguaggio:** TypeScript 5.7 - **Database & ORM:** SQLite via Drizzle ORM + `@libsql/client` - **Interfaccia:** Tailwind CSS v4, Radix UI, Lucide React - **Test & Qualità:** Node.js Native Test Runner, ESLint, pre-push automated Git hooks - **Deploy:** Container Docker orchestrato su Synology NAS #### Funzionalità Chiave - State machine con milestones per flussi Officina (preventivo, autorizzazione, lavorazione, consegna) e Nuovo (bisarca, targhe, installazione satellitare). - Allarme automatico per ritardo oltre 48h nello stato di autorizzazione flotta. - Gestione dinamica flotte con assegnazione colore perimetrale a 360° per rapida identificazione visiva. --- ### PII Redactor Lite Repository: https://github.com/AlexMaina05/pii-redactor-lite Applicazione intelligente e reversibile per la sanitizzazione di testi contenenti dati personali identificabili (PII - Personally Identifiable Information). #### Funzionalità Chiave - Riconoscimento contestuale ed estrazione entità tramite Google Gemini Flash-Lite. - Sostituzione con token crittografici reversibili per permettere la successiva de-anonimizzazione autorizzata. - Massima efficienza e latenza minima grazie a modelli LLM leggeri e compatti. --- ### CAD Parametrico 3D Web Repository: https://github.com/AlexMaina05/3d-model Applicazione web client-side per la progettazione CAD parametrica e l'esportazione di file STL/STEP ottimizzati per la stampa 3D FDM/SLA. #### Stack Tecnologico - TypeScript + Replicad - OpenCascade kernel compilato in WebAssembly (WASM) per rendering ed estrusione geometrica interamente in-browser. --- ## 3.
