Yiğit Güldal — economics, data and software, built under the sun

Website  /  Radio  /  Links  /  YouTube  /  X  /  LinkedIn  /  Get in touch

I'm Yiğit Güldal, a.k.a. lordon1a. I study economics at Anadolu University and build software where markets, data and systems meet — from server-security plugins in Java to a real-time CRM in Flask, plus a few sunny experiments on the web.

I care about tools that make complex systems legible: who can see what, which signals matter, and how data becomes a decision. Some of my work is open source; the rest is private, but you'll find what it does below.

Start here

01 / SERVER SECURITY

SunshineCommandGuard

Hide commands from tab-complete, block their execution and keep your plugin list private — scoped per LuckPerms group, with an admin tool that explains every decision.

Get the plugin → 		02 / INVESTIGATION

Sunshine Sentinel

Turns scattered anti-cheat flags, blocked commands and world activity into one explainable risk timeline per player — and into reviewable incidents.

03 / PRODUCT · 🔒 PRIVATE

Portfiva CRM

A WhatsApp-first CRM for real-estate teams: pipelines, messaging, workflow automation and AI assistance on a modular Flask + PostgreSQL monolith.

Read the case study → 		04 / LIVE

Sunshine Radio

A shared YouTube radio in a sunlit 3D room: everyone hears the same song, votes the queue and chats — while a turntable spins on the desk.

On the workbench: Sunshine Bubbles

Soap-bubble effects and abilities for a Minecraft server.

Custom GLSL shaders draw the bubbles on the client, and a Paper plugin spawns and manages them with five abilities on top. It already runs in production behind a Velocity proxy.

In active development. The codebase is currently private.

More things I've built
