Jex
About this gig
I'm Jex, an independent game developer from France. I've been building games since 2016, and Roblox is where I ship the most.
I script in Luau and build complete games in Roblox Studio, from a single system to a full release. I already released Reborn Leveling, an action RPG on Roblox, and I'm building a tycoon right now.
What I can do for you:
- Gameplay systems: combat, quests, tycoon droppers, rounds, pets, inventories
- Saving with DataStores, leaderboards, admin tools
- UI that works on PC, mobile and console
- Monetization: game passes, developer products, premium payouts
- Multiplayer done right: server-side checks, anti-exploit, smooth replication
- Performance: fewer lag spikes, lighter scripts, better FPS on phones
How I work:
- You get the place file and all source code
- Clean, commented scripts your team can keep working on
- Progress updates with videos so you see the game grow
- I reply quickly, in English or French

FAQ
Can you fix or add to my existing Roblox game?
Yes. Invite me to the experience in Team Create or send the place file. I read your code first and tell you what I'll change before I start.
Do I get the source code?
Always, in every package. Everything I write is yours.
Do you make the 3D models and art too?
I can build simple maps, UI and effects. For a unique art style or complex models, I work with your artist or your assets.
Will it work on mobile?
Yes. I test on PC and phone controls, and UI is built to scale on every screen.
How do we communicate?
Through Fiverr messages. I send short video updates along the way so you always know where the project is.
