🏛️ About

EUR-UN is an independent, open-source engineering collective based in Europe with a globally distributed contributor base. We build practical tools in the domains of network infrastructure, cybersecurity, intelligent automation, and IoT — with a strong commitment to multilingual accessibility (EN / 中文 / FR / CZ) and open governance.

Our work spans from low-level encryption middleware to satellite-imagery-driven data science, unified by a single philosophy: ship reliable, well-documented software that solves real-world problems.

🗂️ Project Portfolio

All projects are organized by domain. ★ marks organization-originated projects; the rest are maintained community forks.

🌐 Network Infrastructure & Observability

Project Stack Description
RouteLens Go TypeScript Go-powered network lens for pinpointing latency & packet loss across Local / Backbone / DC segments. 24/7 stealth monitoring via SSH — zero traffic impact, GFW/QoS resistant.
CdnOriginUpdater Shell Automated scripts to fetch and update origin IP/CIDR blocks for major CDNs (Cloudflare, CloudFront, EdgeOne, etc.) — essential for firewall whitelisting.
EZ-Encrypt-Middleware Go Open-source encryption middleware. 53 forks — one of our most community-adopted projects.

🤖 Intelligent Automation & GovTech

Project Stack Description
VisaStatusMonitor Python Full-process visa & residence-permit status tracking system with automatic push notifications, multi-user support, and modular architecture for rapid extension.
Czech-Visa-Application-Status-Check Python Batch generation of visa query codes and automated application status checking — streamlining a traditionally manual and error-prone process.

🔐 Security & Privacy

Project Stack Description
CertDeliver Python TLS/SSL certificate distribution service for multi-node deployments. Licensed under GPL-3.0.
FormVault Python Securely collects client PII and document uploads (student ID, passport photos, etc.) via a clean frontend with a simple admin backend.
Error-1402 HTML Static error-page template used to disguise / mask the real backend service — useful as a honeypot decoy or anti-enumeration layer.

🏠 IoT & Home Automation

Project Stack Description
SmartHome_Server Python MQTT Smart home sensor control & automation using MQTT, Home Assistant, and Unix-like servers. Includes Mosquitto / EMQX broker config and prototype automation scripts.

📊 Data Science & AI

Project Stack Description
★ EY_Challenge_2026 Jupyter Python Satellite-imagery-driven data science for the EY Open Science Challenge 2026 — water quality analysis using Landsat/Sentinel data, deep learning, and geospatial tooling.

🛠️ DevOps & System Utilities

Project Stack Description
LazyMount-Mac Shell A robust macOS mount manager for NAS gamers. Auto-mounts SMB & Rclone, detects network status, and auto-repairs "dirty" APFS sparsebundles to fix Steam "Disk Write Error" issues. 3 forks.

💼 Enterprise & Finance

Project Stack Description
ERPNext-Czech-Uctova-Osnova-COA-Converter Python Converts the Czech public-sector chart of accounts (Účtová Osnova) to ERPNext-ready multilingual CSV (CZ / EN / ZH), aligned with IPSAS/CAS terminology.

🎓 Academic & Research

Project Stack Description
BE5B35LSP-Logic-Systems-and-Processors VHDL Course materials and lab implementations for Logic Systems & Processors (BE5B35LSP) at Czech Technical University in Prague (ČVUT).
CVUT-SZZ-Survival-Kit Docs Comprehensive study materials, notes, and cheat sheets for the State Final Examination (SZZ) at ČVUT — an open knowledge base for students.

📐 Engineering Principles

Principle Practice
Accuracy over hype Every README describes what the code actually does — no inflated claims.
Multilingual by default Documentation ships in EN / 中文 / FR, with CZ where relevant to Czech tools.
Open-source first We default to MIT; use GPL-3.0 only when copyleft propagation is intentional.
Production-grade CI, tests, and structured error handling are expected — not optional.
Modular architecture Projects are designed for extensibility — plug in, don't rewrite.

🤝 Community & Governance
