About Me

I'm an experienced Roblox programmer that specialises in system designs. I can develop complex tasks like Custom Networking, Custom Physics Replication, Custom Physics, Voxel Destructions and Combat System. If you need simple tasks, I can also put together abilities from resources, create a weather system and fully working UI frontend.

Storyboard is a strictly typed unified sequence engine, specifically designed for combat. It abstracts networking complexity and maximise reusability with Components. It has a built in context management pipelne to handle predictive client actions or general context communication between server and client.

Highly performant and optimised system for real time voxelisation destructions and debris replicating. It uses Separating Axis Theorem recursively to find the smallest expected part from larger parts. Parallel Luau is utilised to make the entire thing faster and more performant.

This inventory UI, Frontend Coding and Backend Coding is completed in 7h within a day of dedicated working.

A rigid inventory system designed with data safety in mind. It is designed fundementally to prevent duplication exploits and data issues. (This is open source so you can check if you click here)

Why Me?

Professional workflow, secure systems designs, and responsiveness.

01 DevOps & Tooling

Modern Professional Workflow

I use a modern Roblox development pipeline using Rojo and Git + GitHub, it enables professional source control, modular code management, and higher efficiency. Alternatively, I am also prepared to work directly in Roblox Studio with only the necessary packages if the project requires it.

02 Architecture

Craftsman Framework Integration

All of my systems are built on top of the Craftsman Framework, a modular Roblox framework engineered for high concurrency environments. Craftsman is a framework tailored to boost efficiency to the next level, so hours of time are not spent on writing common or repetitive code.

lua

1local Craftsman = {
2	Component = Component, -- Module Loader
3	Player = Player, -- Player Management
4	Entity = Entity, -- Character & Entity Management
5	Queue = Queue, -- Task Queue System
6
7	DataServer = DataServer, -- Server Data Manipulation
8	DataClient = DataClient, -- Client Data Access
9	MarketServer = MarketServer, -- Server Marketplace Logic
10	MarketClient = MarketClient, -- Client Marketplace Access
11
12	InputUtil = InputUtil, -- User Input Handling
13	PrintUtil = PrintUtil, -- Debugging and Printing
14	TableUtil = TableUti, -- Table Manipulation Utilities
15
16	AnimationUtil = AnimationUtil, -- Animation Handling
17	SoundUtil = SoundUtil, -- Sound Handling
18
19	MathUtil = MathUtil, -- Math Utilities
20	StringUtil = StringUtil, -- String Utilities
21
22	Config = Config, -- Configuration Management
23}

03 Security

Reliable Systems Design

Security and optimisation is the foundation of all systems. Using transaction queueing, strict server authority, and network binary serialization, my systems compress payloads to the absolute minimum while preventing common bugs like item duplication.

lua

1-- Secure first in first out transaction queue to ensure race conditions bugs do not create the opportunity for critical bugs such as item dupes in complex inventory interactions.
2local function get_transaction_queue(player: Player)
3	local queue = transaction_queues[player]
4	if not queue then
5		queue = Craftsman.Queue.new({
6			RetryOn = false,
7			DefaultTimeout = 4,
8		})
9		transaction_queues[player] = queue
10	end
11
12	return queue
13end
14
15-- Requests a transaction for the player, it will be queued and executed sequentially to prevent async race conditions
16local function request_transaction(player: Player, callback)
17	local queue = get_transaction_queue(player)
18	local promise = queue:Enqueue(function()
19		return Promise.new(function(resolve, reject)
20			Craftsman.DataServer:UpdateState(
21				player, function(state)
22				local new_state = Craftsman.TableUtil.DeepClone(state)
23				callback(new_state, resolve, reject)
24				return new_state
25			end)
26		end)
27	end)
28
29	return promise
30end
