FiveM Server Developer

I build complete FiveM servers — systems, UI, vehicles & infrastructure.

Full-stack FiveM developer behind Heróis do Mar RP, a large-scale production roleplay server. From custom Lua systems and in-game UI to 3D car work and the Proxmox infrastructure it runs on — I ship it all, on a live server, with zero downtime.

What I do

One developer, the whole stack

Most FiveM jobs need three people. I cover gameplay code, the interface, the 3D assets and the servers underneath.

Custom Systems & Scripts

Gameplay systems built from scratch or deeply customized in Lua — economy, vehicles, phone apps, jobs and more.

NUI / Frontend

Responsive in-game interfaces, HUDs, dashboards and minigames in HTML/CSS/JS — fast, clean and exploit-aware.

Vehicles & 3D

Add-on car de-badging, texture optimization (up to −80% footprint) and MLO / map integration.

Jobs & Economy

Balanced, anti-exploit job loops with server-authoritative payouts and a central XP / progression system.

Server Infra & DevOps

Proxmox cluster, MariaDB, zero-downtime hot deploys, monitoring and automated backups.

Security & Audits

Code audits, anti-cheat, exploit fixing — including removal of real RCE backdoors from leaked resources.

Selected work

Things I've shipped on HMRP

A sample of features running right now on a live, paid roleplay server.

System

Uber with NPC Fallback

Ride-hailing job with real drivers and automatic NPC passengers when nobody's online. Server-side meter, phone request flow and billing integration.

UI · Frontend

Police / EMS MDT

Tactical mobile data terminal: fines, records, searches and mugshots — fully translated to Portuguese and wired into the billing system.

Vehicles

Realistic Vehicle Failure

Physics-based engine degradation that bridges pushing dead cars and mechanic repairs. Carefully calibrated so damage feels fair, not punishing.

System · Phone

In-Phone Billing & Invoices

Police, EMS and mechanics issue invoices straight from the phone. Server-authoritative payments feeding department vaults and commissions.

3D · Optimization

Car De-badge & Optimization

End-to-end pipeline that strips brand marks (textures and 3D geometry) and cuts streaming footprint by up to −81% — collisions intact.

UI · Anti-cheat

Immersive Heist Minigames

Four house-robbery minigames with token-based anti-cheat and session-safe overlays so old timers never close the wrong screen.

System · Web

VIP & Coins Store

Web-to-game VIP store with functional perks — extra houses, VIP garages and salary boosts — all validated server-side.

DevOps

Zero-Downtime Deploys

Per-resource hot restarts on a live server with players online, on a 2-node Proxmox cluster with full 24/7 monitoring.
