Bio

I study electrotechnics and automotive IT at BMSZC Bolyai János Technical School. My work sits between software, infrastructure, electronics, live production, and networking.

I also work with event technology, including lighting, audio, visual effects, special effects, and electrical systems for concerts and live events.

On the software side, I build tools, dashboards, bots, automation scripts, monitoring systems, and self-hosted services using Linux, Windows, Proxmox, Docker, Nginx, PHP, Node.js, Python, and Bash.

I am also working toward HAREC certification to expand further into RF communication, amateur radio, and emergency communications.

Overview

I like building systems that connect the digital and physical world: servers, scripts, dashboards, lighting control, field networks, monitoring, and automation. My focus is not one specific stack; it is building reliable workflows that solve real problems.

Current direction: combining homelab automation, event infrastructure, and field-ready networking into portable, resilient technical setups.

Technical Focus

Infrastructure

  • Proxmox virtualization
  • Docker and containerized services
  • Nginx reverse proxies and web hosting
  • Monitoring, alerting, and backups

Development

  • Full-stack web tools and dashboards
  • Backend APIs and automation controllers
  • Batch, Bash, Python, PHP, JavaScript, C/C++
  • Practical scripts that evolve into frameworks

Networking

  • Routing, DHCP, DNS, VLANs, VPNs
  • Portable networks for events and field setups
  • Wireless access, interference mitigation, and uptime planning
  • Server-to-server links and redundant access paths

Event Technology

  • Lighting rigs and DMX-style workflows
  • Audio systems and live technical operation
  • Power distribution and electrical safety
  • Show networks and temporary infrastructure

Systems I Use

  • Linux for servers, development, automation, and infrastructure work.
  • Windows for compatibility, testing, tools, and certain production workflows.
  • VS Code for scripting, web development, and multi-language projects.
  • Visual Studio for larger C/C++ and .NET workflows.
  • Terminal-first workflow using Bash, PowerShell, and shell automation.

Languages & Tools

Low-Level / Desktop

  • C
  • C++
  • Java
  • .NET / C# basics

Web

  • HTML / CSS / JavaScript
  • Node.js
  • PHP
  • Nginx deployments

Scripting / Automation

  • Python
  • Bash
  • Batch
  • PowerShell
  • Lua

PowerEdge R630 Compute Cluster

  • Multiple Dell PowerEdge R630 nodes
  • Dual 14-core CPUs per node
  • Up to 56 threads per node
  • ECC memory and mixed SSD/HDD storage
  • Hypervisor: Proxmox VE
  • Workloads: web services, Minecraft infrastructure, backend/frontend systems, testing environments
  • Networking: routed access, tunnels, gateway integration, and backup paths

IBM Storage Nodes

  • ECC-based storage systems
  • TrueNAS CORE with IPMI management
  • RAID boot storage
  • Multi-drive HDD pools with cache storage
  • Role: file storage, compression, backups, and internal data management

Portable HomeLab

A compact field-ready setup designed for temporary networks, events, remote access, and mobile infrastructure.

  • Huawei 4G CPE used as the primary mobile uplink.
  • TP-Link ER706W Omada gateway for routing, firewall, VPN, and DHCP.
  • Custom UPS-backed power setup for portable operation and low downtime.
  • Two Raspberry Pi 3B+ nodes for lightweight compute and independent services.
  • Samsung M.2 SSD storage for portable data and service hosting.
  • Cudy outdoor PoE access point for wireless coverage.

Event Experience

I have worked on live events, concerts, and parties where the technical side mattered as much as the program itself: power distribution, lighting, audio, network reliability, cabling, and operational safety.

My largest hosted setup so far was a 9th-grade welcome party with over 170 attendees. The build involved a full concert-style technical deployment: digital mixers, moving heads, rod lights, strobes, subwoofer arrays, top speakers, microphones, patching, long cable runs, and a dedicated event network.

My role focused heavily on networking and reliability: custom RouterBox deployment, interference mitigation, anti-jamming considerations, and communications planning to keep the production network stable during the event.

Note: power and electrical work should always be planned and checked according to local regulations, site limits, and proper safety procedures.

Networking & Integration

  • Low-latency links between compute and storage nodes.
  • Routed access between services, gateways, and backup paths.
  • DNS, DHCP, firewall, VPN, and reverse-proxy integration.
  • Experience with LAN-party and Minecraft server infrastructure under heavy load.
  • Portable network design for events and temporary deployments.

SpaceCraftMC Infrastructure

  • Velocity proxy with region-based routing and forced-host logic.
  • Multi-node server layout running on Dell R630 infrastructure.
  • Automated restarts, monitoring, and patched plugin stacks.
  • Designed for scalability, service separation, and controlled backend routing.

KRÉTA / xDev School Tools

  • Schedule and countdown tools with a secure backend controller.
  • JSON-based caching and fast frontend updates.
  • Modular PHP structure for easy extension and maintenance.
  • Designed for school dashboards, kiosk displays, and internal tools.

Projects

OMEGA / BatchRack

OMEGA is an experimental Batch-based command environment focused on control, persistence, plugin loading, encryption experiments, and Windows automation.

  • OMEGA I: early command shell and parser foundation.
  • OMEGA II: plugin loading, basic security layers, and filesystem simulation.
  • OMEGA III: encryption experiments and isolation concepts.
  • BatchRack / OMEGA IV: integrated kernel-style runtime with plugins and sandbox persistence.

Purpose: pushing Windows Batch beyond normal scripting use and exploring how far a constrained environment can be extended.

RPlotSquared Builds

Private patched build workflow using Gradle. This is build and integration work, not original ownership of the upstream source.

Automation

I automate repetitive infrastructure work wherever it makes sense: systemd services, Bash scripts, Python utilities, scheduled backups, dynamic DNS updates, monitoring hooks, and Discord-based alerts.

The goal is simple: fewer manual steps, faster recovery, cleaner visibility, and less time wasted repeating the same fix twice.
