Project Solution

Gauss Development delivered native iOS and Android mobile apps with a PHP-based backend focused on a frictionless onboarding and self-service car-sharing workflow. Users register, locate and unlock cars at predetermined spots, drive, and return vehicles to designated locations. The vendor also implemented administrative functionality — including invoicing/discount tools, customer statistics, a call-centre task manager, multi-vehicle support, real-time tracking/control, analytics to match demand, and role-based secure access. A core team of four (project manager, front-end designer, and two senior developers) executed the work.
