Main Quest : Build things, keep them running, improve them.
Greetings! I'm Jacatinelord, also known as Yuuya.
The alias Yuuya was inspired by Yuuya Marino from Crush Gear Turbo.
I'm a developer from Indonesia who enjoys working across an entire system rather than staying inside only one layer of it.
I usually find myself somewhere between:
- 🌐 Full-stack web development
- 🎮 Game server development
- ⚙️ Backend systems
- 🗄️ Database management
- 🖥️ Server administration
- 🌍 Networking & reverse proxies
- 🔧 Deployment, maintenance & troubleshooting
- 💬 Technical / community support
- 🧪 Random experiments that somehow become real projects
I like understanding how everything connects — from the frontend a user sees to the server, database, proxy, and services running behind it.

Web, game-server, and custom software development hub. GarudaDev is where I bring together the different sides of my development work — from websites and backend systems to game-server development, infrastructure, integrations, and long-term maintenance. What it represents:
|
Aether for locally hosted services. System Eternia is a networking/tunneling platform built to make a locally hosted game server, website, or application reachable from the internet — including environments where a normal public IP is unavailable. It combines my interests in networking, agents, tunnels, service routing, infrastructure, and self-hosting.
|
|
Long-running World of Warcraft private-server project. A project where I work across the entire stack: game core, scripting, databases, website, networking, deployment, maintenance, administration, and player support.
|
Not everything I build is available in a public repository. I've also worked on private, commissioned, internal, and client projects involving web systems, game servers, hosting infrastructure, integrations, databases, deployment, maintenance, and troubleshooting. Some repositories remain private because they contain client code, internal systems, credentials/configuration structures, licensed assets, or project-specific implementations.
|
GitHub only shows part of what I work on. A significant portion of my development history lives in private repositories and deployed systems.
Sinmeowgra is my main long-term personal project.
I handle a mixture of programming, web development, server operations, infrastructure, maintenance, administration, and technical support.

My web-development work is mostly centered around PHP / Laravel applications and systems that need to interact with databases, users, business workflows, or game services.

Some systems I've worked on include:
- Laravel authentication systems
- Role / permission management
- POS and cashier systems
- Product and inventory-related workflows
- Purchasing modules
- Supplier and category management
- Product catalog interfaces
- Administrative dashboards
- Analytics and reporting interfaces
- Game server ↔ website integration
- Database-backed applications
A lot of my work happens where users never see it.
I enjoy figuring out how services communicate, how they're exposed to the internet, how they fail, and how to keep them alive.
