Personal projects

Ultimate Setup Hub

Ultimate Setup Hub is a platform I’m currently building for the Le Mans Ultimate simracing community. It’s designed to be the go-to hub for:

Sharing and discovering car setups across different tracks and conditions
Getting AI help and guidance on improving your setups
Using an advanced strategy calculator to plan multi-stint races down to the finest detail

Whether you’re chasing milliseconds in time trials or planning your next 24-hour race, Ultimate Setup Hub aims to give drivers the tools they need to go faster, smarter, and further.

The project combines my passion for simracing and engineering, and I’m building it from the ground up with performance, usability, and community in mind.
