Custom Scripts & Systems
Gameplay systems, economy logic, and server events in Lua for ESX Legacy — scoped with you, delivered configurable and documented.
// about
One developer. Real production load.
I'm Big_F, the developer behind LuaLabs. I build custom FiveM scripts for ESX Legacy roleplay servers — backend logic, NUI interfaces, and Scaleform work — running in production at 1,000+ concurrent players.
Everything ships under the av_ prefix: built for one server's exact needs, and tuned until it holds up under real load.
// services
What gets delivered
UI, NUI & Scaleform
Interfaces players actually use: NUI overlays, Scaleform HUD work, and hybrid setups that stay smooth at high player counts.
Server Infrastructure & Optimization
Entity pooling, density control, and performance passes for servers where “runs fine on 64 slots” isn’t good enough.
// selected work
Scripts in production
av_redeem
Redeem-code system for vehicles, currency, items, and faction packages — server-side validation with Discord webhook logging.
av_minimap
Hybrid Scaleform + NUI minimap replacement with per-player persistence.
av_vehicle_pool + av_npc_density
Combined vehicle-pool and NPC-density control keeping entity budgets stable on large-scale servers.

How an engagement works
Scope
You describe what your server needs; we pin down exact behavior, edge cases, and ESX integration points before anything is written.
Build
I write the script and you get progress builds to test on a dev server along the way.
Handover
Final delivery with config documentation and integration support until it runs clean on your box.
