CentralRP V2
Independent systems. One believable world.
CentralRP is a custom ESX Legacy roleplay environment built around connected experiences instead of isolated resources.
01
The challenge
A modern roleplay server contains dozens of products: banking, government, companies, documents, vehicles and personal devices. The challenge was to make them feel like parts of one world, not separate scripts.
02
The approach
I design, develop and integrate the systems across Lua, JavaScript, NUI and MySQL — aligning the logic, data, permissions and interfaces so actions in one product have meaningful effects elsewhere.
01Connected data
02Consistent interfaces
03Practical performance
Live CentralRP ecosystem
Try the complete devices.
Choose a phone, tablet or full PC. Every device runs its original HTML, CSS and JavaScript interface with installed apps and safe demo data.
The entire device is always fitted into the frame. Demo actions stay in your browser and never connect to the private FiveM server or production database.
Original CentralRP interfaces running in browser-only demo mode, without access to the private server or production data.

About · 06Patrik Slíška
Developer by choice.Problem solver by nature.
PS.
I combine software development with a practical technical background. My education in electrical engineering and information technology shaped the way I approach systems: understand how every part works, then make the whole dependable.
Alongside development, I lead technical work on construction projects. That real-world responsibility carries into software — clear planning, direct communication and solutions that work outside the presentation deck.

Product mindset
Logic, data and interface designed as one experience
How I work · 0701—04
Clarity at every stage.
Good development is not only clean code. It is a shared understanding of the problem, deliberate decisions and a result that remains useful after delivery.
01
Understand the system
I map the users, rules, data and dependencies before choosing the implementation.
02
Build the right layer
I turn the plan into maintainable logic and an interface that supports the real workflow.
03
Connect and verify
I integrate the moving parts, test edge cases and refine performance before handover.
04
Communicate clearly
You always know what is done, what comes next and which decisions need your input.
