Roblox · Luau · Systems development

Roblox gameplay and backend systems, built to be maintained.

I develop gameplay, backend services, persistent data, interfaces, and moderation tooling in Luau, structured so a team can extend the work after launch.

Nathaniel Madrid, the freelance programmer behind Cynex Services

Systems that stay clear, stable, and readable.

I am a Roblox programmer and systems developer studying computer science with a game-development focus. My work covers gameplay systems, DataStore architecture, responsive UI, moderation tools, NPC behaviour, economies, and internal development tooling.

I organise projects around reusable Luau modules, server-side validation, predictable state, and explicit configuration, so the result stays practical for a team to extend.
