I mainly work with Lua, ESX, JavaScript, HTML/CSS, MySQL, oxmysql, ox_lib and other common FiveM technologies.
My services can include:
Custom FiveM scripts
ESX integrations
Job and faction systems
Banking and economy systems
Vehicle systems
Discord integrations
Admin and management tools
Custom interactions
ox_lib and ox_target integrations
ox_inventory integrations
MySQL / oxmysql databases
Custom NUI interfaces
HTML, CSS and JavaScript
Existing script modifications
Bug fixing and debugging
Performance optimization
Server-specific systems and features
I focus on practical, configurable and maintainable resources instead of generic copy-paste solutions.
Every custom project is discussed before development so the required features, framework and scope are clearly defined.
Please contact me before ordering larger or complex systems.
