I need a seasoned FiveM developer who can take a QBCore framework and turn it into a polished, fully custom role-play environment. The brief is straightforward: start from a clean slate, architect the entire server, weave in advanced systems, and leave me with a modern, fast, and maintainable build that feels purpose-made rather than pieced together. What matters most is technical depth. You should be comfortable writing or refactoring scripts, linking everything through a clean UI, and obsessing over performance so tick rates stay rock-solid even during peak events. Expect to handle economy logic, law-enforcement and medical mechanics, custom jobs, housing, inventories, and whatever else we finalise after our kickoff call—always with optimisation front of mind. I am not interested in template drops or recycled code; show me past QBCore or comparable FiveM work that proves you can craft systems from scratch. Once I see that, we will map out the full feature list, milestones, and hand-off documentation together. If you thrive on building premium RP servers that last, let’s talk.
