01 / ABOUT ME

A developer’s mindset.
A systems perspective.

Built on hands-on experience.

I’m Gary, a Full Stack Developer and System Engineer who sees the application and its infrastructure as one connected system.

My background spans web development, Windows Server administration, databases, networking, and technical support. I bring that practical perspective to building applications: how people use them, how their data moves, and how they operate after deployment.

From PHP and MySQL websites to Microsoft SQL Server administration and production web servers, I work across the layers that make a web application useful and maintainable.

ADMINISTRATION & GAME TOOLS

Web-Based Control Panel

Web application

Cipher Panel brings game administration tools into a browser-based workspace. Its item list editor connects searchable item selections with item-code conversion, game server selection, and character lookup.

The interface also brings together navigation for mail, player rankings, gift codes, maintenance, and user management.
