Database-connected bot that automates whitelisting, schedules backups, logs activity, and sends role-based DM broadcasts to new players.

Smoke Grenade

Server-authoritative smoke grenade system with screen blur, synchronized timers, and anti-abuse safeguards for tactical gameplay.

Gasmask

Wearable item that negates smoke/gas effects while providing clear UI feedback, fully integrated with permission checks.

Energy Drink

Consumable that removes stamina drain and grants temporary speed boosts, featuring configurable cooldowns and expiry timers.

Mining Job (XP/VIP)

Mining job with fixed spots, animations, progress tracking, an experience & leveling system, VIP multipliers, and randomized rewards.

Placeable Storage

Ground-placed storage items that turn into temporary containers, integrated with the inventory system and auto-cleanup logic.

Tyre Steal & Repair

Realistic wheel removal and repair using a wrench, with synchronized vehicle states and detailed staff logging for moderation.

Money Laundering

Dynamic laundering spots with a chance to alert police, rewards scaled by level/VIP, and full integration into the economy.

Dismantle & Recovery

Vehicle dismantling yields 25% of its value, while recovery costs 40%, creating a realistic risk/reward balance for players.

Race System

Custom race system with checkpoints inspired by The Crew, synchronized timers, and leaderboard-ready architecture.

Welcome Message

Automated welcome messages on spawn, configurable by staff commands, often used to highlight events or server announcements.

Bus Driver Job

Discord Log System

All-in-one logging resource that standardizes rich embeds across the server (payments, robberies, tuning, admin actions). Single script handles channels, markdown formatting, rate-limit safety, and consistent fields (player name, passport, amounts, items, plate, etc.), making audit trails clear and searchable.

Wall Script

Staff-only overlay that displays floating player names, source IDs, and passports above heads—visible only to staff who enable it. Shows a red [WALL] tag when both staff members have the tool active, with crisp outlines and centered typography for readability.

Armored Truck Heist

Stockade robbery built from scratch: crowbar requirement, server-driven progress, milestone police alerts, and global cooldowns. Integrates a dedicated Robber skill with XP/level-ups, plus dynamic risk/reward scaling and clean, staff-friendly logging.

Skill / XP System

Universal progression framework where players level roles like Robber and Miner. Grants tangible bonuses (reduced action time, payout multipliers), with clear notifications, persistent storage, and easy hooks for new activities and jobs.

Core Gameplay Systems

  • Networking & Sync: server-authoritative states, entity net-sync, anti-abuse timers.
  • Persistence: inventory, attachments, ammo, player data, and tunings stored safely.
  • Economy & Banking: secure debits/credits, audit logs, recovery and rollback paths.
  • Combat & Items: status effects (smoke/gasmask), buffs (energy drink), clean equip/unequip.
  • Police/Crime Loops: laundering with alert probability, dismantle vs recovery risk balancing.
  • Activities & Progression: mining with XP/levels/VIP, races with checkpoints and timing.

About Gabriel

Designer, programmer, and community builder from Portugal

I am Gabriel "Synthix" Silva, a Portuguese gameplay programmer, designer, and content creator. I thrive on crafting unique concepts and taking on challenges across design, coding, and gaming.

I have been scripting in Lua/FiveM for over 5 years with a deep focus on roleplay systems. Before that, I was building mods and scripts from age 11, which taught me how to design core gameplay mechanics and multiplayer systems from the ground up.

Design has always been part of the journey: I started in Photoshop back when the logo was still the feather, sharpening my eye for branding, UI polish, and advertisement that now elevates every game project I touch.

Today I’m transitioning that systems mindset into Unreal Engine, blending Blueprints and C++ toward fully remote roles across indie, startup, and tools teams. Alongside Medusa development I publish a daily Dev Diary sharing tasks, progress, and learnings with the community.

Objective

My goal is to secure a full-time remote gameplay programming role where I can grow and evolve while contributing to live projects — moving beyond part-time work and applying the multiplayer systems expertise I’ve built through years of server development.
