The clients behind the work

Every entry here is a real engagement with a page of its own. Where a client asked to stay unnamed, the project appears without a name rather than with an invented one — and the numbers stay exactly as measured.

TransLog Solutions

A fleet-management platform that replaced paper route sheets for Romanian logistics operators — vehicle records, driver assignment, fuel consumption and compliance reporting in one place.

What used to be mountains of paper route sheets is now a digital platform our drivers actually use. They understood our logistics problem before they wrote any code.Andrei MarinescuCEO, TransLog Solutions
