Summary
🤩
RockstarZerio is a Sweden-based web developer with six years of hands-on experience building and securing full-stack systems, particularly within the FiveM gaming ecosystem. He contributes across front-end and back-end, from UI fixes and spawn interfaces to server-side Lua logic, database-integrated character management, and admin/security hardening. His open-source work on the popular QB-Core framework includes removing exploits, adding permission checks and ban systems, and improving code clarity—demonstrating a pragmatic focus on reliability and abuse prevention. He’s also contributed to mainstream tooling like Beekeeper Studio, adding a JSON editor to its table view, showing an ability to improve developer UX beyond game mods. Not obviously apparent from his title, he blends game-server ops, security-conscious backend engineering, and front-end polish in a single practical skillset.
