Freelance developer

I build bots, sites, games and apps.

Discord bots, websites, Roblox games, and custom Windows apps. I've shipped all four, and I'll build whatever your project needs. Tell me the idea and I'll quote it.

What I make

Four things I build well. Prices are starting points; tell me what you're after and I'll give you a real number once I know the scope.

Discord

Roblox

Roblox games

A whole game, or one system dropped into yours. Built with Rojo and Luau.

  • Combat, shops, saving, UI
  • Mobile and PC support

Desktop

Windows apps

Custom desktop tools, launchers, and tailored clients in C# and .NET.

  • Native .NET / WPF apps
  • Custom clients and launchers
  • Quoted per project
from £120

I can host anything I build and keep it online for you, or hand over the code to run yourself. Your call.

Stuff I've built

Real, shipped projects across all four. Several you can go and try right now.

Scrapline

Roblox game

A co-op top-down survivor game on Roblox. Pick a class, grab a gun, and survive 20 waves of enemies with up to three friends. Built from nothing: wave spawning, classes, level-up upgrades, shops, bosses, and saved progress that carries between sessions.

All-in-one community bot

Discord bot

Runs a whole game's community off a single bot. Staff get full mod tools, the server gets automatic spam and raid protection, members level up as they chat, support runs through tickets, and there's a live player count pulled straight from the game's API. Two more bots behind it: a daily-reminder automation bot and a data-driven game reference bot.

Specced

Web app

A free revision platform for GCSE and A-Level students. Structured lessons across multiple subjects, built to scale from one course to many. Live at specced.pages.dev.

Multi-course platform Physics, Chemistry, Biology, Maths Cloudflare Pages Built to grow

sayer.pages.dev

Website

My personal site, and a showcase of front-end work: 46 browser games and 51 tools I wrote, all running right in the page with no game engine behind them. Just hand-written JavaScript.

46 games 51 tools No frameworks Live site

Feathercord

Desktop app

A lightweight Discord client for Windows. A WebView2 wrapper around the real Discord with a hard cache cap, so it cold-loads faster than the heavier alternatives without bundling anything extra.

Windows / WebView2 Lighter than the alternatives Custom client

Flexstrap

Desktop app

A custom Roblox bootstrapper and an alternative to Bloxstrap. Installs and launches the Roblox engine itself, built in C# on .NET 8 with WPF.

How it works

Low risk for you. You get to watch it work before you pay the rest.

Tell me the idea

A sentence is enough to start. I'll confirm the scope and give you a price.

I build it

You'll get updates as it comes together, not weeks of silence.

You see it working

I show you the thing actually running before you pay the rest.

It goes live

I hand it over with everything you need to run it, and I'll host it if you want.

Want something built?

Tell me what you've got in mind and I'll come back with a price and a rough timeline.
