"Medals" is a comprehensive web platform designed to revolutionize performance tracking for athletes and coaches. It provides a centralized, secure, and user-friendly solution to record, analyze, and visualize performance metrics.
- For Athletes: A personal digital trophy case to log achievements and track progress.
- For Coaches: A command center to monitor team performance and manage administrative overhead.
- Tech Highlights: Role-based security, data visualization, and CSV bulk imports.
The system is built on a robust Java Spring Boot backend and a responsive React frontend, containerized with Docker.
| Component | Description | Repository |
|---|---|---|
| Backend | Java Spring Boot REST API handling auth, logic, and data structures. | medals-backend |
| Frontend | React + TypeScript SPA providing the interactive dashboard. | medals-frontend |
| Deployment | Docker Compose & Nginx configuration for containerized deployment. | medals-deployment |
The Digital Caretaker for Game Servers.
Status: 🚧 In Development
Cosy is an open-source platform for the orchestration and management of game servers (like Minecraft, Valheim, or CS:GO). Unlike typical administrative dashboards, Cosy features a unique "village" aesthetic where servers are represented as buildings in a pixel-art world.
- Cost Efficiency: Optimized for performance on single-host systems (Root servers/VPS) with optional Kubernetes scaling.
- Isolation: Every game server runs in its own Docker container.
- Advanced Observability: Uses Loki for log aggregation (allowing live console streaming via WebSockets) and InfluxDB for performance metrics.
- Hybrid Runtime: Runtime-agnostic design (Docker local or Kubernetes cluster).
Cosy utilizes a microservices approach with a Java monolith for control and a high-performance Rust service for external APIs.
| Component | Description | Repository |
|---|---|---|
| Backend | Java Spring Boot application acting as the central control center and log router. | Cosy-Backend |
| Frontend | React + TypeScript (Bun) interface rendering the "Village" UI. | Cosy-Frontend |
| Game API | Rust microservice for fetching game assets (icons/art) from external sources. | Cosy-Gameapi |
| Release | The official Cost Optimized Server Yard download repo. | Cosy |
| Deployment | Kubernetes (K8s) configuration files for modern cloud deployment. | Cosy-Deployment |
| Landing | Public-facing marketing and information page. | Cosy-Landing-Page |
| Templates | COSY Templates — Official and community-maintained JSON templates for Docker Compose and Kubernetes used by COSY. | Cosy-Templates |
