IT Operations · Full-stack · Automation & AI
I build small, reliable tools that keep IT running: web apps, monitoring, dashboards, automation and AI agents.
- Monitoring & uptime: self-hosted status pages, network/LAN monitors and Telegram alerts
- Helpdesk & IT asset management: ticketing, QR asset tracking and dashboards
- Automation: Python/Node scripts, n8n workflows, scheduled reports, content pipelines
- Web apps: React + TypeScript front ends with Node.js/Express APIs, from database to UI
- AI & agents: Claude Code with MCP connectors, LLM features in production (document/receipt extraction)
- Search & RAG: hybrid BM25 + embedding search, cited answers, offline local models (see rag-demo below)
- Linux & DevOps: VPS setup, Docker, Nginx, SSL, backups and hardening
| Repo | What it does |
|---|---|
| book-lending-app | Full-stack library app: React + TypeScript, Express REST API, SQLite, tests, CI and Docker |
| vps-hardening | Secure a fresh Ubuntu/Debian VPS in one run: SSH keys only, UFW, fail2ban, auto updates |
| backup-monitor-telegram | Nightly check that backups are fresh and not empty, with one Telegram summary |
| rag-demo | Ask questions about a folder of documents and get answers with sources, or an honest "not in the documents". Hybrid search, works offline |
| selfhosted-monitoring-stack | Uptime Kuma + Caddy (auto HTTPS) + daily backups in one docker compose up |
| Project | What it does | Stack |
|---|---|---|
| IT Ops & Monitoring Platform | Uptime, LAN and internet monitoring with alerts and a public status page | Node.js · Docker · Uptime Kuma · Telegram |
| Helpdesk & Asset Management | Ticketing, QR-coded IT assets and a division-wide dashboard | PHP/Node · MySQL · Chart.js |
| Fleet & Driver Ops | Scheduling and tracking for 30+ vehicles and drivers | Node.js · PostgreSQL · CI/CD |
| Digital Library | Catalogue and lending for 17,000+ books | Web app · MySQL |
| Content Automation | Scheduled Instagram and LinkedIn posting from a content calendar | Python · Playwright · Meta & LinkedIn APIs |
| andriarezki.tech | This portfolio and its small self-hosted services | HTML/CSS/JS · Nginx |
Most of this work is internal or client work, so the code is private. Case studies and demos are on andriarezki.tech.
