Message

At Save Co, I built TypeScript middleware to integrate HubSpot and Bitrix24, replacing a third-party vendor and cutting annual operating costs from BRL 70K to about BRL 600. I provisioned the AWS infrastructure and migrated workflows without downtime.

As a QA Analyst at Save Co, I established the QA function and implemented 172 automated tests, raising coverage from 0% to 70% and reducing production errors by 85%. Earlier, I supported enterprise integrations at Adapcon and SAP Business One users at WEG S.A.
