I will script secure roblox game systems in typed luau
Angelina Builes
About this gig
I am a Roblox developer and QA engineer with shipped Luau work behind me. I build the systems your game needs and I make sure they hold when players try to break them.
What you get:
Server side validation on everything. The client never decides rewards, currency or progress, so exploiters get nothing.
DataStore persistence that survives session errors, with retries and no lost saves.
Live ops systems: shops, currency with sources and sinks, gacha, purchases with receipt idempotency, badges, referrals and leaderboards.
FTUE and tutorial flows with funnel analytics, so you can see exactly where players quit.
Typed Luau in strict mode, modular and commented, handed over so your team can keep building on it.
Recent work: over 80 Luau modules for a branded Roblox experience, one island delivered solo with 28 game services and anti exploit checks, and a published collectible card game with 8 live ops systems.
I also spent 4 years in software QA, including UEFN titles tested under Epic Games certification standards. You get tested code with reproduction steps, not a zip file and good luck.
Tell me what your game needs and I will tell you honestly if I am the right fit.

FAQ
Do you work with an existing game or only from scratch?
Both. I can drop systems into a game you already have, or build the core from zero. If it is an existing game, send me the place file or a copy so I can see how it is structured before we agree on scope.
Will the code be readable by my own developers?
Yes. Typed Luau in strict mode, split into modules, with comments on the parts that are not obvious. The Standard and Premium packages include a handover document explaining how the systems connect.
Can players exploit what you build?
Nothing important is decided on the client. Currency, rewards, progress and purchases are validated on the server, and purchases are idempotent so a repeated receipt never grants twice. I have built anti exploit checks across 28 game services.
Do you test what you deliver?
Yes, and this is where I am different from most sellers here. I worked 4 years in software QA, including UEFN titles tested under Epic Games certification standards. Every delivery is tested before it reaches you.
What if I do not like the result?
Every package includes revisions. Tell me what is wrong and I fix it. If the scope changes into something we never agreed on, I will tell you honestly and we quote it separately instead of dragging the order.
What time zone are you in?
Colombia, UTC minus 5. That overlaps with Eastern Time all day and with Pacific Time most of the working day.
Do you sign an NDA?
Yes, no problem.
