I'm David, a 26-year-old undergraduate Computer Science Engineering student at the University of Pécs, Faculty of Engineering and Information Technology, with a dual focus on software development and systems engineering.
I specialize in cross-platform application development using C# and Java, and I manage self-hosted infrastructure and services with tools like Proxmox VE, Docker, and Linux-based networking. Whether it's designing modular software or deploying reliable infrastructure, I enjoy working across the full stack of both development and operations.
- C# / .NET: AvaloniaUI, ASP.NET Core (Blazor, WebAPI, MinimalAPI), EF Core, .NET Core
- Java: Spring Boot, Spring Security, Spring Data, Thymeleaf
- Others: Lua, HTML/CSS/JS, SQL, JSON
- CwATE-MA: A web content management system (WCMS) powered by Microsoft ASP.NET Core
- CwATE-SB: A web content management system (WCMS) powered by Spring framework
- CwATE Theme: Theming and UI layer for the CwATE ecosystem

- Visual Studio, JetBrains Rider, IntelliJ IDEA
- GitHub, Git CLI
- Docker & Docker Compose
- Package hosting: Private NuGet and Maven repositories
- Cross-platform mobile/desktop apps with Microsoft MAUI
- Cloud-native Java development
- Running Proxmox VE 8+ (migrated from VMware ESXi in late 2023)
- Containerized deployments using Docker
- LXC/KVM virtualization with internal and public network segmentation
I operate a multi-server environment consisting of:
- A dedicated server in Germany for all public-facing production services
- A home production server for internal services and backups
- Multiple homelab/tinkering servers for testing, learning, and experiments
Main services include:
- Reverse proxy stack (Docker-based)
- VPN and DNS servers
- Monitoring stack using Grafana and Prometheus
- Game server panel for personal use
- Dockerized web applications based on CwATE-MA and CwATE-SB
- Various custom utilities and containerized tools
