Roblox's TextGenerator just gives you text back. No agents, no tool calling. I wanted NPCs in my game that could actually look stuff up and do things, so I built that part myself.

Watch me make a game
Design the UI, code it, build the level, then playtest. Very sped up, but that's honestly the order I do it in.

The code, structure & worlds behind Aura
Aura is a game I made solo. This is its real project structure, so click around. The orange tags open actual code.

Puts Roblox's Input Action System into named groups. Each group gets its own InputContext, so I can turn a whole control scheme on, off or change its priority in one line.

AI & open source
I build AI agents (and give the tools away)
Most of this started because I needed it for my own games. If it turned out useful, I put it on the DevForum for free.

DevForumTOON for Luau
TOON (Token-Oriented Object Notation) in Luau. It's like JSON without all the brackets and repeated keys, so you use fewer tokens and pay less. Heads up though: if your data is deeply nested, just stick with JSON.

Benchmark from the postSend Discord messages from your game with typed embeds, Color3 colors, TTS, custom usernames and swappable proxies. You can spot AdvancedWebhook in Aura's explorer up there too.

Other stuff I've made
One of the first UI particle emitters on Roblox, back in 2022. You design particles in a plugin, pick a UI element, and it writes the script for you. I capped it at 100 particles and tested it on a 2GB RAM laptop. It's archived now though: every particle is its own chain of tweens, and that doesn't scale.

How I figure things out
I try to find what's actually wrong before I fix anything. Here are a few real ones, with links so you can check.
- What I noticedIt wasn't Discord. Cloudflare was rate limiting Roblox's server IPs on discord.com because of how many requests they sent.
- What I didI sent requests through Discord's old discordapp.com domain and made the proxy swappable, so if one route gets blocked you just switch.
- What I noticedI couldn't make the model smarter, but I could make its job easier. Small models do way better with flat, one-line output.
- What I didMade SLC, a looser way to match tool names, and tools the model can use to look up other tools. If it invents a tool, the error tells it the real ones.
- What I noticedMost game data is basically a table, so you only need to write the field names once.
- What I didWrote a TOON encoder in Luau. 118 tokens went down to 70 on my test. I also said where not to use it: nested data should stay JSON.
- What I noticedIf it runs fine on the worst device, it runs fine everywhere.
- What I didCapped it at 100 particles and tested on a 2GB RAM laptop with built-in graphics. When it got outdated, I marked it archived instead of letting people keep using it.
How I write code
Any style, any case
Whatever naming, framework or structure your codebase already uses, I'll fit in. No need to rewrite everything my way. If it's up to me though, I'm going OOP.
Naming cases
tap one to copyGo on, type your own.
Paradigms
Same feature (giving a player coins), four ways.
What I do
Stuff I can build for your game
Gameplay systems
Combat, inventories, zones, leaderboards, clans. Built so they're easy to add onto later.
Data & backend
Saving player data safely, plus moderation tools and logs.
AI agents & NPCs
NPCs and agents that can look things up and actually do stuff in your game, not just chat.
Monetization
Game passes and dev products that don't feel pushy.
Prompt engineering
Prompts that keep the AI on track, give clean output and don't burn through tokens.
Discord & web integrations
Discord bots, webhook logs and websites for your studio.
Input & UI
Controls that feel good on PC, console and mobile.
Prototype to launch
I made Aura by myself, so I can handle one feature or a whole game.
Environment design
Worlds that look good and make players want to explore.
Got a project?
I take projects I can do well.
How I work
From “hey, I need…” to done
Same five steps every time. Tap a step to see what happens there.
How pricing works
- Small system
- from $50
- Medium system
- from $200
- Large system
- from $800
- AI / NPC integration
- from $300
- Hourly $25-$40
- Part-time retainer from $1,200/month
Final quote depends on scope. Larger projects use milestone payments.
Projects over ~$300: 30-50% deposit or milestones. Logs + video before final payment, files after.
USD preferred. Robux only in some cases, revenue % only with a signed agreement. No middlemen.
Before hiring me, give my terms a quick read.
Why it costs what it costs
You see one button. I build everything under it.
A shop button looks like ten minutes of work. Making sure nobody can exploit it, nobody loses their stuff, and it still works when Roblox is having a bad day? That's the actual job, and it's most of the time you're paying for.
Try it: hit Buy, or spam it like an exploiter would.
Cheap usually skips this part
You find out after launch, when exploiters dupe items or players lose their progress.
Fixing it later costs more
Rebuilding a broken economy with live players is way harder than building it right once.
You pay for the time it takes
No padding. A bigger backend takes more time, and small stuff stays small.
So no, I'm not the cheapest. But what I hand over is built to keep working after I'm gone.
What players see
1,250
Speed Potion
500
What actually runs when they press it ↓
1 button, 7 systems
Debounce the click
Double clicks and lag spikes don't buy it twice.
Ask the server
The client never decides anything. Exploiters can make it say whatever they want.
Validate everything
Is the item real? Can they afford it? Are they spamming? Checked on the server.
Take coins, give item
Both happen or neither does. No free items, no lost coins.
Save it safely
Session locking and retries, so data doesn't get lost or duped when DataStores act up.
Log it
Sent to your Discord, so you can see what sells and spot anything weird.
Handle the weird stuff
Player leaves mid purchase, server shuts down, inventory full. All covered.
+ testing all of it against exploits, lag and servers shutting down.

Why hire me
Here's what you get when you hire me
I've been building on Roblox since 2018, and I treat your project like my own game. I care how it performs after launch, not just that it works today.
I also think before I build. A lot of problems are easier than they look once you figure out what's actually going wrong, and that's the part I'm good at.
I focus on what I do best. If you need something outside that, like advanced VFX or modeling, I'll tell you upfront instead of winging it. But game systems, AI and pulling the whole thing together? That's my thing.
I actually finish things
Aura was just me, start to finish. Players averaged about 1,362 minutes in it.
See the statsMore than a scripter
Systems, UI, websites and Discord tooling, plus help with marketing. Fewer people for you to manage.
See my workYou can check my work
My code and resources are public on GitHub and the DevForum. Look before you hire.
Open source stuffReliable communication
Clear scope and deadlines up front, regular progress updates, and I reply within 24h. You always know where your project stands.
All in
Once I start, your project gets my full attention and my best work. No half effort.
Honest opinions
If something won't work, I'll say so before you spend money on it, and explain why.
