About Me

Who's actually doing the work

I've spent a long time in the Metin scene — building systems, hunting bugs, and getting called in when a server's own team couldn't figure out what was breaking. I stepped away for a while. Now I'm back, taking on work again.

Same way of working as always: you message me, you tell me what you need, I get into it . No forms, no back-and-forth just to figure out what you want.

What I can do

[Custom]

Systems from scratch

I build systems from scratch, turning a simple idea into something that works properly in practice, with clean, high-quality code that fits the game's architecture.

[Fixes]

Bug & exploit fixes

I fix issues and exploits caused by custom systems, as well as those originating from the mainline codebase.

[Crash]

Unexpected crashes & packet issues

Unknown packets, random disconnects, or teleport crashes — diagnosed and fixed, with automated reporting when needed.

[Debugging]

Performance optimization

Diagnosing and resolving complex issues involving system instability, memory leaks, service slowdowns, and difficult-to-trace performance bottlenecks.

[Tools]

Automation

Building custom tools to automate repetitive tasks, reduce manual work, and streamline specialized technical workflows.
