Caio M.

Data Engineer

Caio er en allsidig dataprofesjonell med over fem års erfaring fra programvare- og datateknikk, datavitenskap og analyse.

I tillegg påtok Caio seg en sentral rolle i Nubank, hvor han ledet et team på 200 fagfolk, og styrte initiativet Data Governance and Cost Accountability. Dette initiativet økte innsynet i prosjekt- og oppgaverelaterte kostnader betydelig, til fordel for alle involverte teammedlemmer.

I løpet av sin periode i Accenture viste Caio eksepsjonelt engasjement da han jobbet flittig med å implementere GCP Data-løsninger i kundenes infrastruktur. Denne innsatsen hadde stor innvirkning, og effektiviserte datainnsamlingsprosessen betydelig fra ulike kilder og reduserte tiden som tidligere ble brukt på manuell datainnsamling.
